Given numbers are 987, 733, 421, 386
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 733) = 723471
GCD(987, 733) = ( 987 x 733 ) / 723471
= 987 / 733
= 987
Step2:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
Step3:
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
= 1 / 386
= 1
So, Greatest Common Divisor of 987, 733, 421, 386 is 1
