Given numbers are 818, 490, 435, 238

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

Apply this formula for all numbers.

Step1:

LCM(818, 490) = 200410

GCD(818, 490) = ( 818 x 490 ) / 200410

= 818 / 490

= 818

Step2:

LCM(2, 435) = 870

GCD(2, 435) = ( 2 x 435 ) / 870

= 2 / 435

= 2

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 818, 490, 435, 238 is 1
