Given numbers are 111, 780, 472, 561

The list of prime factors of all numbers are

Prime factors of 111 are 3 x 37

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

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

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 111, 780, 472, 561

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

Apply this formula for all numbers.

Step1:

LCM(111, 780) = 28860

GCD(111, 780) = ( 111 x 780 ) / 28860

= 111 / 780

= 111

Step2:

LCM(3, 472) = 1416

GCD(3, 472) = ( 3 x 472 ) / 1416

= 3 / 472

= 3

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 111, 780, 472, 561 is 1
