Given numbers are 257, 337, 490, 254

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

Apply this formula for all numbers.

Step1:

LCM(257, 337) = 86609

GCD(257, 337) = ( 257 x 337 ) / 86609

= 257 / 337

= 257

Step2:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 257, 337, 490, 254 is 1
