Given numbers are 990, 955, 643, 183
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 955) = 189090
GCD(990, 955) = ( 990 x 955 ) / 189090
= 990 / 955
= 990
Step2:
LCM(5, 643) = 3215
GCD(5, 643) = ( 5 x 643 ) / 3215
= 5 / 643
= 5
Step3:
LCM(1, 183) = 183
GCD(1, 183) = ( 1 x 183 ) / 183
= 1 / 183
= 1
So, Greatest Common Divisor of 990, 955, 643, 183 is 1
