Given numbers are 720, 455, 388, 751

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 455 are 5 x 7 x 13

Prime factors of 388 are 2 x 2 x 97

Prime factors of 751 are 751

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

Given numbers are 720, 455, 388, 751

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

Apply this formula for all numbers.

Step1:

LCM(720, 455) = 65520

GCD(720, 455) = ( 720 x 455 ) / 65520

= 720 / 455

= 720

Step2:

LCM(5, 388) = 1940

GCD(5, 388) = ( 5 x 388 ) / 1940

= 5 / 388

= 5

Step3:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1

So, Greatest Common Divisor of 720, 455, 388, 751 is 1
