Given numbers are 355, 167, 487, 720

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 167 are 167

Prime factors of 487 are 487

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

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

Given numbers are 355, 167, 487, 720

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

Apply this formula for all numbers.

Step1:

LCM(355, 167) = 59285

GCD(355, 167) = ( 355 x 167 ) / 59285

= 355 / 167

= 355

Step2:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 355, 167, 487, 720 is 1
