Therefore, GCD of numbers 636, 258, 65, 715 is 1

Given Input Data is 636, 258, 65, 715

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 258 is 2 x 3 x 43

Prime Factorization of 65 is 5 x 13

Prime Factorization of 715 is 5 x 11 x 13

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(636, 258) = 27348

GCD(636, 258) = ( 636 x 258 ) / 27348

GCD(636, 258) = 164088 / 27348

GCD(636, 258) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 65

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

LCM(6, 65) = 390

GCD(6, 65) = ( 6 x 65 ) / 390

GCD(6, 65) = 390 / 390

GCD(6, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 715

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

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

GCD(1, 715) = 715 / 715

GCD(1, 715) = 1

GCD of 636, 258, 65, 715 is 1
