Given numbers are 210, 213, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 213) = 14910
GCD(210, 213) = ( 210 x 213 ) / 14910
= 210 / 213
= 210
Step2:
LCM(3, 921) = 921
GCD(3, 921) = ( 3 x 921 ) / 921
= 3 / 921
= 3
So, Greatest Common Divisor of 210, 213, 921 is 3
