Given numbers are 631, 225, 386, 648

The list of prime factors of all numbers are

Prime factors of 631 are 631

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 386 are 2 x 193

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 631, 225, 386, 648

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

Apply this formula for all numbers.

Step1:

LCM(631, 225) = 141975

GCD(631, 225) = ( 631 x 225 ) / 141975

= 631 / 225

= 631

Step2:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 631, 225, 386, 648 is 1
