Given numbers are 687, 885, 481, 972

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 885 are 3 x 5 x 59

Prime factors of 481 are 13 x 37

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 687, 885, 481, 972

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

Apply this formula for all numbers.

Step1:

LCM(687, 885) = 202665

GCD(687, 885) = ( 687 x 885 ) / 202665

= 687 / 885

= 687

Step2:

LCM(3, 481) = 1443

GCD(3, 481) = ( 3 x 481 ) / 1443

= 3 / 481

= 3

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 687, 885, 481, 972 is 1
