Given numbers are 648, 274, 621, 631

The list of prime factors of all numbers are

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

Prime factors of 274 are 2 x 137

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 631 are 631

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

Given numbers are 648, 274, 621, 631

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

Apply this formula for all numbers.

Step1:

LCM(648, 274) = 88776

GCD(648, 274) = ( 648 x 274 ) / 88776

= 648 / 274

= 648

Step2:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 648, 274, 621, 631 is 1
