Given numbers are 721, 471, 657, 198

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 471 are 3 x 157

Prime factors of 657 are 3 x 3 x 73

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 721, 471, 657, 198

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

Apply this formula for all numbers.

Step1:

LCM(721, 471) = 339591

GCD(721, 471) = ( 721 x 471 ) / 339591

= 721 / 471

= 721

Step2:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

Step3:

LCM(1, 198) = 198

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

= 1 / 198

= 1

So, Greatest Common Divisor of 721, 471, 657, 198 is 1
