GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(418, 779) = 17138
GCD(418, 779) = ( 418 x 779 ) / 17138
= 418 / 779
= 418
Step2:
LCM(19, 208) = 3952
GCD(19, 208) = ( 19 x 208 ) / 3952
= 19 / 208
= 19
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 418, 779, 208, 257 is 1
