Given numbers are 645, 656, 633, 508

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 633 are 3 x 211

Prime factors of 508 are 2 x 2 x 127

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

Given numbers are 645, 656, 633, 508

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

Apply this formula for all numbers.

Step1:

LCM(645, 656) = 423120

GCD(645, 656) = ( 645 x 656 ) / 423120

= 645 / 656

= 645

Step2:

LCM(1, 633) = 633

GCD(1, 633) = ( 1 x 633 ) / 633

= 1 / 633

= 1

Step3:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

So, Greatest Common Divisor of 645, 656, 633, 508 is 1
