Given numbers are 990, 189, 423, 800
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 189) = 20790
GCD(990, 189) = ( 990 x 189 ) / 20790
= 990 / 189
= 990
Step2:
LCM(9, 423) = 423
GCD(9, 423) = ( 9 x 423 ) / 423
= 9 / 423
= 9
Step3:
LCM(9, 800) = 7200
GCD(9, 800) = ( 9 x 800 ) / 7200
= 9 / 800
= 9
So, Greatest Common Divisor of 990, 189, 423, 800 is 1
