Given numbers are 720, 286, 57, 756

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 286 are 2 x 11 x 13

Prime factors of 57 are 3 x 19

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 720, 286, 57, 756

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

Apply this formula for all numbers.

Step1:

LCM(720, 286) = 102960

GCD(720, 286) = ( 720 x 286 ) / 102960

= 720 / 286

= 720

Step2:

LCM(2, 57) = 114

GCD(2, 57) = ( 2 x 57 ) / 114

= 2 / 57

= 2

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 720, 286, 57, 756 is 1
