Given numbers are 637, 420, 981, 877

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 981 are 3 x 3 x 109

Prime factors of 877 are 877

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

Given numbers are 637, 420, 981, 877

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

Apply this formula for all numbers.

Step1:

LCM(637, 420) = 38220

GCD(637, 420) = ( 637 x 420 ) / 38220

= 637 / 420

= 637

Step2:

LCM(7, 981) = 6867

GCD(7, 981) = ( 7 x 981 ) / 6867

= 7 / 981

= 7

Step3:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

So, Greatest Common Divisor of 637, 420, 981, 877 is 1
