Given numbers are 672, 655, 173, 647

The list of prime factors of all numbers are

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 655 are 5 x 131

Prime factors of 173 are 173

Prime factors of 647 are 647

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

Given numbers are 672, 655, 173, 647

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

Apply this formula for all numbers.

Step1:

LCM(672, 655) = 440160

GCD(672, 655) = ( 672 x 655 ) / 440160

= 672 / 655

= 672

Step2:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 672, 655, 173, 647 is 1
