GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(986, 399) = 393414
GCD(986, 399) = ( 986 x 399 ) / 393414
= 986 / 399
= 986
Step2:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 986, 399, 210 is 1
