Given numbers are 720, 858, 137, 117

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 858 are 2 x 3 x 11 x 13

Prime factors of 137 are 137

Prime factors of 117 are 3 x 3 x 13

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

Given numbers are 720, 858, 137, 117

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

Apply this formula for all numbers.

Step1:

LCM(720, 858) = 102960

GCD(720, 858) = ( 720 x 858 ) / 102960

= 720 / 858

= 720

Step2:

LCM(6, 137) = 822

GCD(6, 137) = ( 6 x 137 ) / 822

= 6 / 137

= 6

Step3:

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

= 1 / 117

= 1

So, Greatest Common Divisor of 720, 858, 137, 117 is 1
