GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 909) = 19998
GCD(198, 909) = ( 198 x 909 ) / 19998
= 198 / 909
= 198
Step2:
LCM(9, 646) = 5814
GCD(9, 646) = ( 9 x 646 ) / 5814
= 9 / 646
= 9
Step3:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
So, Greatest Common Divisor of 198, 909, 646, 285 is 1
