Given numbers are 721, 162, 855, 477

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 477 are 3 x 3 x 53

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

Given numbers are 721, 162, 855, 477

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

Apply this formula for all numbers.

Step1:

LCM(721, 162) = 116802

GCD(721, 162) = ( 721 x 162 ) / 116802

= 721 / 162

= 721

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1

So, Greatest Common Divisor of 721, 162, 855, 477 is 1
