Given numbers are 966, 980, 991, 154

The list of prime factors of all numbers are

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 991 are 991

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 966, 980, 991, 154

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

Apply this formula for all numbers.

Step1:

LCM(966, 980) = 67620

GCD(966, 980) = ( 966 x 980 ) / 67620

= 966 / 980

= 966

Step2:

LCM(14, 991) = 13874

GCD(14, 991) = ( 14 x 991 ) / 13874

= 14 / 991

= 14

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 966, 980, 991, 154 is 1
