Given numbers are 508, 603, 454, 420

The list of prime factors of all numbers are

Prime factors of 508 are 2 x 2 x 127

Prime factors of 603 are 3 x 3 x 67

Prime factors of 454 are 2 x 227

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 508, 603, 454, 420

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

Apply this formula for all numbers.

Step1:

LCM(508, 603) = 306324

GCD(508, 603) = ( 508 x 603 ) / 306324

= 508 / 603

= 508

Step2:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 508, 603, 454, 420 is 1
