Given numbers are 630, 539, 972, 556

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 539 are 7 x 7 x 11

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

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 630, 539, 972, 556

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

Apply this formula for all numbers.

Step1:

LCM(630, 539) = 48510

GCD(630, 539) = ( 630 x 539 ) / 48510

= 630 / 539

= 630

Step2:

LCM(7, 972) = 6804

GCD(7, 972) = ( 7 x 972 ) / 6804

= 7 / 972

= 7

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 630, 539, 972, 556 is 1
