Given numbers are 644, 396, 124, 631

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 124 are 2 x 2 x 31

Prime factors of 631 are 631

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

Given numbers are 644, 396, 124, 631

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

Apply this formula for all numbers.

Step1:

LCM(644, 396) = 63756

GCD(644, 396) = ( 644 x 396 ) / 63756

= 644 / 396

= 644

Step2:

LCM(4, 124) = 124

GCD(4, 124) = ( 4 x 124 ) / 124

= 4 / 124

= 4

Step3:

LCM(4, 631) = 2524

GCD(4, 631) = ( 4 x 631 ) / 2524

= 4 / 631

= 4

So, Greatest Common Divisor of 644, 396, 124, 631 is 1
