Given numbers are 637, 681, 142, 720

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 681 are 3 x 227

Prime factors of 142 are 2 x 71

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 637, 681, 142, 720

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

Apply this formula for all numbers.

Step1:

LCM(637, 681) = 433797

GCD(637, 681) = ( 637 x 681 ) / 433797

= 637 / 681

= 637

Step2:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 637, 681, 142, 720 is 1
