Given numbers are 813, 636, 908, 170
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 636) = 172356
GCD(813, 636) = ( 813 x 636 ) / 172356
= 813 / 636
= 813
Step2:
LCM(3, 908) = 2724
GCD(3, 908) = ( 3 x 908 ) / 2724
= 3 / 908
= 3
Step3:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
So, Greatest Common Divisor of 813, 636, 908, 170 is 1
