Given numbers are 171, 990, 299, 418
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 990) = 18810
GCD(171, 990) = ( 171 x 990 ) / 18810
= 171 / 990
= 171
Step2:
LCM(9, 299) = 2691
GCD(9, 299) = ( 9 x 299 ) / 2691
= 9 / 299
= 9
Step3:
LCM(1, 418) = 418
GCD(1, 418) = ( 1 x 418 ) / 418
= 1 / 418
= 1
So, Greatest Common Divisor of 171, 990, 299, 418 is 1
