GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 858) = 24024
GCD(168, 858) = ( 168 x 858 ) / 24024
= 168 / 858
= 168
Step2:
LCM(6, 981) = 1962
GCD(6, 981) = ( 6 x 981 ) / 1962
= 6 / 981
= 6
Step3:
LCM(3, 702) = 702
GCD(3, 702) = ( 3 x 702 ) / 702
= 3 / 702
= 3
So, Greatest Common Divisor of 168, 858, 981, 702 is 3
