Given numbers are 613, 678, 129, 630

The list of prime factors of all numbers are

Prime factors of 613 are 613

Prime factors of 678 are 2 x 3 x 113

Prime factors of 129 are 3 x 43

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 613, 678, 129, 630

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

Apply this formula for all numbers.

Step1:

LCM(613, 678) = 415614

GCD(613, 678) = ( 613 x 678 ) / 415614

= 613 / 678

= 613

Step2:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 613, 678, 129, 630 is 1
