So the Greatest Common Divisior 70, 12, 86 is 2.

Therefore, GCD of numbers 70, 12, 86 is 2

Given Input Data is 70, 12, 86

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 86 is 2 x 43

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(70, 12) = 420

GCD(70, 12) = ( 70 x 12 ) / 420

GCD(70, 12) = 840 / 420

GCD(70, 12) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 86

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(2, 86) = 86

GCD(2, 86) = ( 2 x 86 ) / 86

GCD(2, 86) = 172 / 86

GCD(2, 86) = 2

GCD of 70, 12, 86 is 2
