Given numbers are 420, 334, 286, 257

The list of prime factors of all numbers are

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

Prime factors of 334 are 2 x 167

Prime factors of 286 are 2 x 11 x 13

Prime factors of 257 are 257

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

Given numbers are 420, 334, 286, 257

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

Apply this formula for all numbers.

Step1:

LCM(420, 334) = 70140

GCD(420, 334) = ( 420 x 334 ) / 70140

= 420 / 334

= 420

Step2:

LCM(2, 286) = 286

GCD(2, 286) = ( 2 x 286 ) / 286

= 2 / 286

= 2

Step3:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

So, Greatest Common Divisor of 420, 334, 286, 257 is 1
