Given numbers are 210, 180, 839, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 180) = 1260
GCD(210, 180) = ( 210 x 180 ) / 1260
= 210 / 180
= 210
Step2:
LCM(30, 839) = 25170
GCD(30, 839) = ( 30 x 839 ) / 25170
= 30 / 839
= 30
Step3:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
So, Greatest Common Divisor of 210, 180, 839, 990 is 1
