Given numbers are 317, 770, 630, 661

The list of prime factors of all numbers are

Prime factors of 317 are 317

Prime factors of 770 are 2 x 5 x 7 x 11

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

Prime factors of 661 are 661

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

Given numbers are 317, 770, 630, 661

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

Apply this formula for all numbers.

Step1:

LCM(317, 770) = 244090

GCD(317, 770) = ( 317 x 770 ) / 244090

= 317 / 770

= 317

Step2:

LCM(1, 630) = 630

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

= 1 / 630

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 317, 770, 630, 661 is 1
