Given numbers are 454, 164, 990, 923
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 164) = 37228
GCD(454, 164) = ( 454 x 164 ) / 37228
= 454 / 164
= 454
Step2:
LCM(2, 990) = 990
GCD(2, 990) = ( 2 x 990 ) / 990
= 2 / 990
= 2
Step3:
LCM(2, 923) = 1846
GCD(2, 923) = ( 2 x 923 ) / 1846
= 2 / 923
= 2
So, Greatest Common Divisor of 454, 164, 990, 923 is 1
