Given numbers are 165, 878, 561, 908
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 878) = 144870
GCD(165, 878) = ( 165 x 878 ) / 144870
= 165 / 878
= 165
Step2:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
Step3:
LCM(1, 908) = 908
GCD(1, 908) = ( 1 x 908 ) / 908
= 1 / 908
= 1
So, Greatest Common Divisor of 165, 878, 561, 908 is 1
