Given numbers are 869, 454, 420, 969

The list of prime factors of all numbers are

Prime factors of 869 are 11 x 79

Prime factors of 454 are 2 x 227

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

Prime factors of 969 are 3 x 17 x 19

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

Given numbers are 869, 454, 420, 969

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

Apply this formula for all numbers.

Step1:

LCM(869, 454) = 394526

GCD(869, 454) = ( 869 x 454 ) / 394526

= 869 / 454

= 869

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

So, Greatest Common Divisor of 869, 454, 420, 969 is 1
