Given numbers are 630, 990, 944, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 990) = 6930
GCD(630, 990) = ( 630 x 990 ) / 6930
= 630 / 990
= 630
Step2:
LCM(90, 944) = 42480
GCD(90, 944) = ( 90 x 944 ) / 42480
= 90 / 944
= 90
Step3:
LCM(2, 166) = 166
GCD(2, 166) = ( 2 x 166 ) / 166
= 2 / 166
= 2
So, Greatest Common Divisor of 630, 990, 944, 166 is 2
