Given numbers are 637, 515, 731, 156

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 515 are 5 x 103

Prime factors of 731 are 17 x 43

Prime factors of 156 are 2 x 2 x 3 x 13

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

Given numbers are 637, 515, 731, 156

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(637, 515) = 328055

GCD(637, 515) = ( 637 x 515 ) / 328055

= 637 / 515

= 637

Step2:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 637, 515, 731, 156 is 1
