Given numbers are 966, 968, 667, 420

The list of prime factors of all numbers are

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

Prime factors of 968 are 2 x 2 x 2 x 11 x 11

Prime factors of 667 are 23 x 29

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 966, 968, 667, 420

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

Apply this formula for all numbers.

Step1:

LCM(966, 968) = 467544

GCD(966, 968) = ( 966 x 968 ) / 467544

= 966 / 968

= 966

Step2:

LCM(2, 667) = 1334

GCD(2, 667) = ( 2 x 667 ) / 1334

= 2 / 667

= 2

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 966, 968, 667, 420 is 1
