Therefore, GCD of numbers 716, 168, 715, 642 is 1

Given Input Data is 716, 168, 715, 642

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

Prime Factorization of 716 is 2 x 2 x 179

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 642 is 2 x 3 x 107

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(716, 168) = 30072

GCD(716, 168) = ( 716 x 168 ) / 30072

GCD(716, 168) = 120288 / 30072

GCD(716, 168) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 715

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

LCM(4, 715) = 2860

GCD(4, 715) = ( 4 x 715 ) / 2860

GCD(4, 715) = 2860 / 2860

GCD(4, 715) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 642

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

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

GCD(1, 642) = 642 / 642

GCD(1, 642) = 1

GCD of 716, 168, 715, 642 is 1
