Given numbers are 669, 454, 420, 718

The list of prime factors of all numbers are

Prime factors of 669 are 3 x 223

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 718 are 2 x 359

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

Given numbers are 669, 454, 420, 718

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

Apply this formula for all numbers.

Step1:

LCM(669, 454) = 303726

GCD(669, 454) = ( 669 x 454 ) / 303726

= 669 / 454

= 669

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 669, 454, 420, 718 is 1
