Given numbers are 338, 663, 641, 251

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

Apply this formula for all numbers.

Step1:

LCM(338, 663) = 17238

GCD(338, 663) = ( 338 x 663 ) / 17238

= 338 / 663

= 338

Step2:

LCM(13, 641) = 8333

GCD(13, 641) = ( 13 x 641 ) / 8333

= 13 / 641

= 13

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 338, 663, 641, 251 is 1
