Given numbers are 972, 327, 921, 545

The list of prime factors of all numbers are

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

Prime factors of 327 are 3 x 109

Prime factors of 921 are 3 x 307

Prime factors of 545 are 5 x 109

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

Given numbers are 972, 327, 921, 545

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

Apply this formula for all numbers.

Step1:

LCM(972, 327) = 105948

GCD(972, 327) = ( 972 x 327 ) / 105948

= 972 / 327

= 972

Step2:

LCM(3, 921) = 921

GCD(3, 921) = ( 3 x 921 ) / 921

= 3 / 921

= 3

Step3:

LCM(3, 545) = 1635

GCD(3, 545) = ( 3 x 545 ) / 1635

= 3 / 545

= 3

So, Greatest Common Divisor of 972, 327, 921, 545 is 1
