GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 308) = 16324
GCD(212, 308) = ( 212 x 308 ) / 16324
= 212 / 308
= 212
Step2:
LCM(4, 822) = 1644
GCD(4, 822) = ( 4 x 822 ) / 1644
= 4 / 822
= 4
Step3:
LCM(2, 810) = 810
GCD(2, 810) = ( 2 x 810 ) / 810
= 2 / 810
= 2
So, Greatest Common Divisor of 212, 308, 822, 810 is 2
