Given numbers are 691, 630, 798, 880

The list of prime factors of all numbers are

Prime factors of 691 are 691

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

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

Given numbers are 691, 630, 798, 880

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

Apply this formula for all numbers.

Step1:

LCM(691, 630) = 435330

GCD(691, 630) = ( 691 x 630 ) / 435330

= 691 / 630

= 691

Step2:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

Step3:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

So, Greatest Common Divisor of 691, 630, 798, 880 is 1
