Given numbers are 631, 420, 909, 852

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 909 are 3 x 3 x 101

Prime factors of 852 are 2 x 2 x 3 x 71

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

Given numbers are 631, 420, 909, 852

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

Apply this formula for all numbers.

Step1:

LCM(631, 420) = 265020

GCD(631, 420) = ( 631 x 420 ) / 265020

= 631 / 420

= 631

Step2:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

Step3:

LCM(1, 852) = 852

GCD(1, 852) = ( 1 x 852 ) / 852

= 1 / 852

= 1

So, Greatest Common Divisor of 631, 420, 909, 852 is 1
