Given numbers are 102, 472, 780, 477

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

Prime factors of 472 are 2 x 2 x 2 x 59

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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 102, 472, 780, 477

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

Apply this formula for all numbers.

Step1:

LCM(102, 472) = 24072

GCD(102, 472) = ( 102 x 472 ) / 24072

= 102 / 472

= 102

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 477) = 954

GCD(2, 477) = ( 2 x 477 ) / 954

= 2 / 477

= 2

So, Greatest Common Divisor of 102, 472, 780, 477 is 1
