GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 174) = 23142
GCD(798, 174) = ( 798 x 174 ) / 23142
= 798 / 174
= 798
Step2:
LCM(6, 808) = 2424
GCD(6, 808) = ( 6 x 808 ) / 2424
= 6 / 808
= 6
Step3:
LCM(2, 210) = 210
GCD(2, 210) = ( 2 x 210 ) / 210
= 2 / 210
= 2
So, Greatest Common Divisor of 798, 174, 808, 210 is 2
