Given numbers are 249, 129, 386, 328
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 129) = 10707
GCD(249, 129) = ( 249 x 129 ) / 10707
= 249 / 129
= 249
Step2:
LCM(3, 386) = 1158
GCD(3, 386) = ( 3 x 386 ) / 1158
= 3 / 386
= 3
Step3:
LCM(1, 328) = 328
GCD(1, 328) = ( 1 x 328 ) / 328
= 1 / 328
= 1
So, Greatest Common Divisor of 249, 129, 386, 328 is 1
