Given numbers are 111, 131, 486, 780

The list of prime factors of all numbers are

Prime factors of 111 are 3 x 37

Prime factors of 131 are 131

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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 111, 131, 486, 780

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

Apply this formula for all numbers.

Step1:

LCM(111, 131) = 14541

GCD(111, 131) = ( 111 x 131 ) / 14541

= 111 / 131

= 111

Step2:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 111, 131, 486, 780 is 1
