Greatest Common Divisior

We found the divisors of 36, 87, 70 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 36, 87, 70 is 1.

Therefore, GCD of numbers 36, 87, 70 is 1

Given Input Data is 36, 87, 70

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

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 87 is 3 x 29

Prime Factorization of 70 is 2 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

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(36, 87) = 1044

GCD(36, 87) = ( 36 x 87 ) / 1044

GCD(36, 87) = 3132 / 1044

GCD(36, 87) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 70

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

LCM(3, 70) = 210

GCD(3, 70) = ( 3 x 70 ) / 210

GCD(3, 70) = 210 / 210

GCD(3, 70) = 1

GCD of 36, 87, 70 is 1
