Given numbers are 780, 622, 698, 111

The list of prime factors of all numbers are

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

Prime factors of 622 are 2 x 311

Prime factors of 698 are 2 x 349

Prime factors of 111 are 3 x 37

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

Given numbers are 780, 622, 698, 111

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

Apply this formula for all numbers.

Step1:

LCM(780, 622) = 242580

GCD(780, 622) = ( 780 x 622 ) / 242580

= 780 / 622

= 780

Step2:

LCM(2, 698) = 698

GCD(2, 698) = ( 2 x 698 ) / 698

= 2 / 698

= 2

Step3:

LCM(2, 111) = 222

GCD(2, 111) = ( 2 x 111 ) / 222

= 2 / 111

= 2

So, Greatest Common Divisor of 780, 622, 698, 111 is 1
