GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 654) = 41202
GCD(189, 654) = ( 189 x 654 ) / 41202
= 189 / 654
= 189
Step2:
LCM(3, 549) = 549
GCD(3, 549) = ( 3 x 549 ) / 549
= 3 / 549
= 3
Step3:
LCM(3, 990) = 990
GCD(3, 990) = ( 3 x 990 ) / 990
= 3 / 990
= 3
So, Greatest Common Divisor of 189, 654, 549, 990 is 3
