Given numbers are 477, 111, 581, 780

The list of prime factors of all numbers are

Prime factors of 477 are 3 x 3 x 53

Prime factors of 111 are 3 x 37

Prime factors of 581 are 7 x 83

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

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

Given numbers are 477, 111, 581, 780

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

Apply this formula for all numbers.

Step1:

LCM(477, 111) = 17649

GCD(477, 111) = ( 477 x 111 ) / 17649

= 477 / 111

= 477

Step2:

LCM(3, 581) = 1743

GCD(3, 581) = ( 3 x 581 ) / 1743

= 3 / 581

= 3

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 477, 111, 581, 780 is 1
