Given numbers are 645, 215, 119, 908
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 215) = 645
GCD(645, 215) = ( 645 x 215 ) / 645
= 645 / 215
= 645
Step2:
LCM(215, 119) = 25585
GCD(215, 119) = ( 215 x 119 ) / 25585
= 215 / 119
= 215
Step3:
LCM(1, 908) = 908
GCD(1, 908) = ( 1 x 908 ) / 908
= 1 / 908
= 1
So, Greatest Common Divisor of 645, 215, 119, 908 is 1
