GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 399) = 18753
GCD(987, 399) = ( 987 x 399 ) / 18753
= 987 / 399
= 987
Step2:
LCM(21, 579) = 4053
GCD(21, 579) = ( 21 x 579 ) / 4053
= 21 / 579
= 21
Step3:
LCM(3, 890) = 2670
GCD(3, 890) = ( 3 x 890 ) / 2670
= 3 / 890
= 3
So, Greatest Common Divisor of 987, 399, 579, 890 is 1
