Given numbers are 720, 765, 138, 296

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 765 are 3 x 3 x 5 x 17

Prime factors of 138 are 2 x 3 x 23

Prime factors of 296 are 2 x 2 x 2 x 37

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

Given numbers are 720, 765, 138, 296

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

Apply this formula for all numbers.

Step1:

LCM(720, 765) = 12240

GCD(720, 765) = ( 720 x 765 ) / 12240

= 720 / 765

= 720

Step2:

LCM(45, 138) = 2070

GCD(45, 138) = ( 45 x 138 ) / 2070

= 45 / 138

= 45

Step3:

LCM(3, 296) = 888

GCD(3, 296) = ( 3 x 296 ) / 888

= 3 / 296

= 3

So, Greatest Common Divisor of 720, 765, 138, 296 is 1
