Given numbers are 921, 539, 164, 630

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 539 are 7 x 7 x 11

Prime factors of 164 are 2 x 2 x 41

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 921, 539, 164, 630

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

Apply this formula for all numbers.

Step1:

LCM(921, 539) = 496419

GCD(921, 539) = ( 921 x 539 ) / 496419

= 921 / 539

= 921

Step2:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 921, 539, 164, 630 is 1
