Given numbers are 647, 712, 180, 198

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 712 are 2 x 2 x 2 x 89

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 198 are 2 x 3 x 3 x 11

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

Given numbers are 647, 712, 180, 198

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

Apply this formula for all numbers.

Step1:

LCM(647, 712) = 460664

GCD(647, 712) = ( 647 x 712 ) / 460664

= 647 / 712

= 647

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

So, Greatest Common Divisor of 647, 712, 180, 198 is 1
