Given numbers are 691, 308, 515, 180

The list of prime factors of all numbers are

Prime factors of 691 are 691

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 515 are 5 x 103

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 691, 308, 515, 180

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

Apply this formula for all numbers.

Step1:

LCM(691, 308) = 212828

GCD(691, 308) = ( 691 x 308 ) / 212828

= 691 / 308

= 691

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 691, 308, 515, 180 is 1
