Given numbers are 991, 403, 960, 686

The list of prime factors of all numbers are

Prime factors of 991 are 991

Prime factors of 403 are 13 x 31

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 991, 403, 960, 686

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

Apply this formula for all numbers.

Step1:

LCM(991, 403) = 399373

GCD(991, 403) = ( 991 x 403 ) / 399373

= 991 / 403

= 991

Step2:

LCM(1, 960) = 960

GCD(1, 960) = ( 1 x 960 ) / 960

= 1 / 960

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 991, 403, 960, 686 is 1
