Given numbers are 454, 577, 144, 420

The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 577 are 577

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

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 454, 577, 144, 420

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

Apply this formula for all numbers.

Step1:

LCM(454, 577) = 261958

GCD(454, 577) = ( 454 x 577 ) / 261958

= 454 / 577

= 454

Step2:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 454, 577, 144, 420 is 1
