Given numbers are 720, 136, 387, 731

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 136 are 2 x 2 x 2 x 17

Prime factors of 387 are 3 x 3 x 43

Prime factors of 731 are 17 x 43

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

Given numbers are 720, 136, 387, 731

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

Apply this formula for all numbers.

Step1:

LCM(720, 136) = 12240

GCD(720, 136) = ( 720 x 136 ) / 12240

= 720 / 136

= 720

Step2:

LCM(8, 387) = 3096

GCD(8, 387) = ( 8 x 387 ) / 3096

= 8 / 387

= 8

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 720, 136, 387, 731 is 1
