Given numbers are 177, 512, 859, 420

The list of prime factors of all numbers are

Prime factors of 177 are 3 x 59

Prime factors of 512 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 859 are 859

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 177, 512, 859, 420

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

Apply this formula for all numbers.

Step1:

LCM(177, 512) = 90624

GCD(177, 512) = ( 177 x 512 ) / 90624

= 177 / 512

= 177

Step2:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 177, 512, 859, 420 is 1
