Given numbers are 674, 309, 657, 630

The list of prime factors of all numbers are

Prime factors of 674 are 2 x 337

Prime factors of 309 are 3 x 103

Prime factors of 657 are 3 x 3 x 73

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 674, 309, 657, 630

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

Apply this formula for all numbers.

Step1:

LCM(674, 309) = 208266

GCD(674, 309) = ( 674 x 309 ) / 208266

= 674 / 309

= 674

Step2:

LCM(1, 657) = 657

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

= 1 / 657

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 674, 309, 657, 630 is 1
