Given numbers are 128, 120, 474, 891

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 474 are 2 x 3 x 79

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

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

Given numbers are 128, 120, 474, 891

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

Apply this formula for all numbers.

Step1:

LCM(128, 120) = 1920

GCD(128, 120) = ( 128 x 120 ) / 1920

= 128 / 120

= 128

Step2:

LCM(8, 474) = 1896

GCD(8, 474) = ( 8 x 474 ) / 1896

= 8 / 474

= 8

Step3:

LCM(2, 891) = 1782

GCD(2, 891) = ( 2 x 891 ) / 1782

= 2 / 891

= 2

So, Greatest Common Divisor of 128, 120, 474, 891 is 1
