Given numbers are 647, 168, 174, 440

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 174 are 2 x 3 x 29

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 647, 168, 174, 440

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

Apply this formula for all numbers.

Step1:

LCM(647, 168) = 108696

GCD(647, 168) = ( 647 x 168 ) / 108696

= 647 / 168

= 647

Step2:

LCM(1, 174) = 174

GCD(1, 174) = ( 1 x 174 ) / 174

= 1 / 174

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 647, 168, 174, 440 is 1
