Factors of 42 room the list of confident and negative whole number that can be split evenly right into 42. Negative factors the 42 space just factors with a an adverse sign. The number 42 is far-ranging and is an also composite number which method that it has several factors, in this case, 42 has actually 8 factors. In this lesson, we will certainly calculate the determinants of 42, its prime factors, and also its determinants in pairs. We will also shot a couple of solved instances to recognize this topic better.

What are determinants of 42?
Factors the a number space the numbers which division the provided number precisely without leaving any type of remainder. Factors the 42 room 1, 2, 3, 6, 7, 14, 21 and also 42.
How to calculate the components of 42?
We can use various methods prefer prime factorization and the division method to calculate the determinants of 42. In prime factorization, we express 42 as the product of its prime factors and also in the department method, us look because that numbers that division 42 specifically without a remainder.
Factors of 42 by element Factorization
Prime factorization means expressing a number in terms of the product the its element factors. We deserve to do this using the division method or by utilizing a element tree.
Prime administer by Division:Step 1: The number 42 is separated by the smallest prime number i beg your pardon divides 42 exactly, i.e. It leaves a remainder 0.Step 2: The quotient is then divided by the the smallest or second smallest prime number and the procedure continues it spins the quotient can not be additional divided.Step 3: Let us divide 42 by the prime number 2 i.e 42 ÷ 2 = 21.Step 4: Now we should divide the quotient 21 by the next the very least prime number.Step 5: Since 21 is an odd number, that is not divisible by 2. Allow us shot dividing it by 3 which is 21 ÷ 3 = 7.Step 6: 7 is a prime number and we cannot division it further.Step 7: Therefore, the prime determinants of 42 are 2, 3, and 7.
Prime factorization of 42 = 2 × 3 × 7
Prime administrate by variable Tree
Since we room finding the prime components of 42, they will certainly be placed as the root of our aspect tree. Next, we create a pair of factors (two numbers, when multiplied, give 42) together branches.
3 and 7 are prime numbers and also at this point, the element tree ends. Let us express 42 in regards to the product the its element factors.42 = 2 × 3 × 7
Viola! We have actually done the element factorization. Below is a simple activity to shot on her own. Rather of 2 × 21, if we had used 6 × 7, perform you think us would get the very same factors? have the right to you attract the aspect tree with 6 and also 7 as the branches?
Prime administer by Upside-Down Division
This an approach is called the upside-down division because the department symbol is flipped upside down. In this method, we divide 42 by the the smallest prime number 2 (if the number is odd, we begin with 3). 7 is a element number. The is divisible just by 7. We stop the department when we reach 1.
Therefore, 42 can be expressed together a product the its prime factors together 2 × 3 × 7. Explore factors making use of illustrations and also interactive examples:
Think Tank:8 × 21 ÷ 4 = 42, go this mean 8 and 21 ÷ 4 are determinants of 42? Think!10.5 × 4 = 42, are 10.5 and 4 factors of 42?Can a number better than 42 be its factor?
Factors that 42 in Pairs
Factor pairs space the 2 numbers which, once multiplied, offer the number 42.1 × 42 = 422 × 21 = 423 × 14 = 426 × 7 = 42
Therefore, the pair determinants of 42 room (1,42), (2,21), (3,14), and (6,7). Since the product of two negative numbers is positive, i.e. (-) × (-) = (+), the element pairs that 42 likewise include (-1,-42), (-2,-21), (-3,-14), and also (-6,-7). However let us focus on the positive components in this lesson.
We divide 42 by herbal numbers and see i beg your pardon numbers leaving a remainder 0. The number which divide 42 precisely without any remainder are the components of 42.
Division an approach to Find factors of 42:
We check out that when 42 is split by 1, 2, 3, 6, 7, 14, 21, and also 42, it pipeline no remainder. Hence, lock are determinants of 42.

Important Notes:The numbers which we multiply to obtain 42 space the factors of 42.Factors of 42 room 1, 2, 3, 6, 7, 14, 21, and also 42.1 is a universal factor. The is a element of all numbers. The number chin is a factor of the number as it divides itself exactly.Factor pairs are the pairs of 2 numbers which, when multiplied, offer the number. Variable pairs of 42 are (1, 42), (2, 21), (3,14), and also (6,7).
