Given numbers are 630, 729, 685, 130

The list of prime factors of all numbers are

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

Prime factors of 729 are 3 x 3 x 3 x 3 x 3 x 3

Prime factors of 685 are 5 x 137

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 630, 729, 685, 130

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

Apply this formula for all numbers.

Step1:

LCM(630, 729) = 51030

GCD(630, 729) = ( 630 x 729 ) / 51030

= 630 / 729

= 630

Step2:

LCM(9, 685) = 6165

GCD(9, 685) = ( 9 x 685 ) / 6165

= 9 / 685

= 9

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 630, 729, 685, 130 is 1
