Given numbers are 490, 257, 61, 418

The list of prime factors of all numbers are

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

Prime factors of 257 are 257

Prime factors of 61 are 61

Prime factors of 418 are 2 x 11 x 19

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

Given numbers are 490, 257, 61, 418

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

Apply this formula for all numbers.

Step1:

LCM(490, 257) = 125930

GCD(490, 257) = ( 490 x 257 ) / 125930

= 490 / 257

= 490

Step2:

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

= 1 / 61

= 1

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 490, 257, 61, 418 is 1
