GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(939, 396) = 123948
GCD(939, 396) = ( 939 x 396 ) / 123948
= 939 / 396
= 939
Step2:
LCM(3, 890) = 2670
GCD(3, 890) = ( 3 x 890 ) / 2670
= 3 / 890
= 3
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 939, 396, 890, 987 is 1
