Given numbers are 490, 308, 336, 257

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 257 are 257

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

Given numbers are 490, 308, 336, 257

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

Apply this formula for all numbers.

Step1:

LCM(490, 308) = 10780

GCD(490, 308) = ( 490 x 308 ) / 10780

= 490 / 308

= 490

Step2:

LCM(14, 336) = 336

GCD(14, 336) = ( 14 x 336 ) / 336

= 14 / 336

= 14

Step3:

LCM(14, 257) = 3598

GCD(14, 257) = ( 14 x 257 ) / 3598

= 14 / 257

= 14

So, Greatest Common Divisor of 490, 308, 336, 257 is 1
