Given numbers are 556, 621, 507, 630

The list of prime factors of all numbers are

Prime factors of 556 are 2 x 2 x 139

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 507 are 3 x 13 x 13

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

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

Given numbers are 556, 621, 507, 630

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

Apply this formula for all numbers.

Step1:

LCM(556, 621) = 345276

GCD(556, 621) = ( 556 x 621 ) / 345276

= 556 / 621

= 556

Step2:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 556, 621, 507, 630 is 1
