Given numbers are 490, 409, 268, 248

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

Apply this formula for all numbers.

Step1:

LCM(490, 409) = 200410

GCD(490, 409) = ( 490 x 409 ) / 200410

= 490 / 409

= 490

Step2:

LCM(1, 268) = 268

GCD(1, 268) = ( 1 x 268 ) / 268

= 1 / 268

= 1

Step3:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

So, Greatest Common Divisor of 490, 409, 268, 248 is 1
