Given numbers are 634, 425, 648, 644

The list of prime factors of all numbers are

Prime factors of 634 are 2 x 317

Prime factors of 425 are 5 x 5 x 17

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

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

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

Given numbers are 634, 425, 648, 644

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

Apply this formula for all numbers.

Step1:

LCM(634, 425) = 269450

GCD(634, 425) = ( 634 x 425 ) / 269450

= 634 / 425

= 634

Step2:

LCM(1, 648) = 648

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

= 1 / 648

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 634, 425, 648, 644 is 1
