Given numbers are 631, 416, 396, 945

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

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

Prime factors of 945 are 3 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 631, 416, 396, 945

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

Apply this formula for all numbers.

Step1:

LCM(631, 416) = 262496

GCD(631, 416) = ( 631 x 416 ) / 262496

= 631 / 416

= 631

Step2:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 631, 416, 396, 945 is 1
