Given numbers are 684, 721, 18, 632

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 721 are 7 x 103

Prime factors of 18 are 2 x 3 x 3

Prime factors of 632 are 2 x 2 x 2 x 79

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

Given numbers are 684, 721, 18, 632

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

Apply this formula for all numbers.

Step1:

LCM(684, 721) = 493164

GCD(684, 721) = ( 684 x 721 ) / 493164

= 684 / 721

= 684

Step2:

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

= 1 / 18

= 1

Step3:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

So, Greatest Common Divisor of 684, 721, 18, 632 is 1
