Given numbers are 455, 720, 188, 137

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

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

Prime factors of 188 are 2 x 2 x 47

Prime factors of 137 are 137

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

Given numbers are 455, 720, 188, 137

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

Apply this formula for all numbers.

Step1:

LCM(455, 720) = 65520

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

= 455 / 720

= 455

Step2:

LCM(5, 188) = 940

GCD(5, 188) = ( 5 x 188 ) / 940

= 5 / 188

= 5

Step3:

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

= 1 / 137

= 1

So, Greatest Common Divisor of 455, 720, 188, 137 is 1
