Given numbers are 422, 454, 840, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(422, 454) = 95794
GCD(422, 454) = ( 422 x 454 ) / 95794
= 422 / 454
= 422
Step2:
LCM(2, 840) = 840
GCD(2, 840) = ( 2 x 840 ) / 840
= 2 / 840
= 2
Step3:
LCM(2, 249) = 498
GCD(2, 249) = ( 2 x 249 ) / 498
= 2 / 249
= 2
So, Greatest Common Divisor of 422, 454, 840, 249 is 1
