Given numbers are 497, 420, 641, 584

The list of prime factors of all numbers are

Prime factors of 497 are 7 x 71

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

Prime factors of 641 are 641

Prime factors of 584 are 2 x 2 x 2 x 73

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

Given numbers are 497, 420, 641, 584

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

Apply this formula for all numbers.

Step1:

LCM(497, 420) = 29820

GCD(497, 420) = ( 497 x 420 ) / 29820

= 497 / 420

= 497

Step2:

LCM(7, 641) = 4487

GCD(7, 641) = ( 7 x 641 ) / 4487

= 7 / 641

= 7

Step3:

LCM(1, 584) = 584

GCD(1, 584) = ( 1 x 584 ) / 584

= 1 / 584

= 1

So, Greatest Common Divisor of 497, 420, 641, 584 is 1
