Given numbers are 386, 982, 287, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 982) = 189526
GCD(386, 982) = ( 386 x 982 ) / 189526
= 386 / 982
= 386
Step2:
LCM(2, 287) = 574
GCD(2, 287) = ( 2 x 287 ) / 574
= 2 / 287
= 2
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 386, 982, 287, 129 is 1
