GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 870) = 28710
GCD(990, 870) = ( 990 x 870 ) / 28710
= 990 / 870
= 990
Step2:
LCM(30, 213) = 2130
GCD(30, 213) = ( 30 x 213 ) / 2130
= 30 / 213
= 30
So, Greatest Common Divisor of 990, 870, 213 is 3
