solve the following factories F84 F84=
Answers
Answer:
84
(-4) × (-21) = 84
(-6) × (-14) = 84
(-7) × (-12) = 84
Therefore, the negative pair factors are (-1, -84), (-2, -42), (-3, -28), (-4, -21), (-6, -14) and (-7, -12).
How to Calculate the Factors of 84?
To find the factors, we need to divide the original number with all the natural numbers till we get the value of the quotient equal to 1.
84 ÷ 1 = 84
84 ÷ 2 = 42
84 ÷ 3 = 28
84 ÷ 4 = 21
84 ÷ 6 = 14
84 ÷ 7 = 12
84 ÷ 12 = 7
84 ÷ 14 = 6
84 ÷ 21 = 4
84 ÷ 28 = 3
84 ÷ 42 = 2
84 ÷ 84 = 1
Therefore, the required factors are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84.
Prime Factorisation of 84
84 is a composite number, so the prime factors of 84 can be found using the below steps.
The first step is to divide the number 84 with the smallest prime factor, i.e. 2.
84 ÷ 2 = 42
Again, divide 42 by 2.
42 ÷ 2 = 21
Now, if we divide 21 by 2 we get a fraction number, which cannot be a factor.
Now, proceed to the next prime numbers, i.e. 3, 5, 7 and so on.
21 ÷ 3 = 7
7 ÷ 3 = 2.33, not a factor
Move to next prime number, 5.
Dividing 7 by 5 again gives a fraction value.
7 ÷ 5 = 1.4, not a factor
