Given numbers are 457, 604, 420, 965

The list of prime factors of all numbers are

Prime factors of 457 are 457

Prime factors of 604 are 2 x 2 x 151

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

Prime factors of 965 are 5 x 193

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

Given numbers are 457, 604, 420, 965

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

Apply this formula for all numbers.

Step1:

LCM(457, 604) = 276028

GCD(457, 604) = ( 457 x 604 ) / 276028

= 457 / 604

= 457

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 457, 604, 420, 965 is 1
