Given numbers are 417, 477, 728, 920

The list of prime factors of all numbers are

Prime factors of 417 are 3 x 139

Prime factors of 477 are 3 x 3 x 53

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 417, 477, 728, 920

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

Apply this formula for all numbers.

Step1:

LCM(417, 477) = 66303

GCD(417, 477) = ( 417 x 477 ) / 66303

= 417 / 477

= 417

Step2:

LCM(3, 728) = 2184

GCD(3, 728) = ( 3 x 728 ) / 2184

= 3 / 728

= 3

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 417, 477, 728, 920 is 1
