Given numbers are 648, 314, 435, 645

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 314 are 2 x 157

Prime factors of 435 are 3 x 5 x 29

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 648, 314, 435, 645

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

Apply this formula for all numbers.

Step1:

LCM(648, 314) = 101736

GCD(648, 314) = ( 648 x 314 ) / 101736

= 648 / 314

= 648

Step2:

LCM(2, 435) = 870

GCD(2, 435) = ( 2 x 435 ) / 870

= 2 / 435

= 2

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 648, 314, 435, 645 is 1
