Given numbers are 990, 209, 819, 717
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 209) = 18810
GCD(990, 209) = ( 990 x 209 ) / 18810
= 990 / 209
= 990
Step2:
LCM(11, 819) = 9009
GCD(11, 819) = ( 11 x 819 ) / 9009
= 11 / 819
= 11
Step3:
LCM(1, 717) = 717
GCD(1, 717) = ( 1 x 717 ) / 717
= 1 / 717
= 1
So, Greatest Common Divisor of 990, 209, 819, 717 is 1
