Given numbers are 630, 921, 652, 856

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 921 are 3 x 307

Prime factors of 652 are 2 x 2 x 163

Prime factors of 856 are 2 x 2 x 2 x 107

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

Given numbers are 630, 921, 652, 856

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

Apply this formula for all numbers.

Step1:

LCM(630, 921) = 193410

GCD(630, 921) = ( 630 x 921 ) / 193410

= 630 / 921

= 630

Step2:

LCM(3, 652) = 1956

GCD(3, 652) = ( 3 x 652 ) / 1956

= 3 / 652

= 3

Step3:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 630, 921, 652, 856 is 1
