Given numbers are 637, 921, 440, 554

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 921 are 3 x 307

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 554 are 2 x 277

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

Given numbers are 637, 921, 440, 554

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

Apply this formula for all numbers.

Step1:

LCM(637, 921) = 586677

GCD(637, 921) = ( 637 x 921 ) / 586677

= 637 / 921

= 637

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 637, 921, 440, 554 is 1
