The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

Given numbers are 991, 424, 770, 918

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

Apply this formula for all numbers.

Step1:

LCM(991, 424) = 420184

GCD(991, 424) = ( 991 x 424 ) / 420184

= 991 / 424

= 991

Step2:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

Step3:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

So, Greatest Common Divisor of 991, 424, 770, 918 is 1
