Given numbers are 991, 252, 409, 680

The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 409 are 409

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 991, 252, 409, 680

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

Apply this formula for all numbers.

Step1:

LCM(991, 252) = 249732

GCD(991, 252) = ( 991 x 252 ) / 249732

= 991 / 252

= 991

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 991, 252, 409, 680 is 1
