GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 838) = 205310
GCD(245, 838) = ( 245 x 838 ) / 205310
= 245 / 838
= 245
Step2:
LCM(1, 990) = 990
GCD(1, 990) = ( 1 x 990 ) / 990
= 1 / 990
= 1
Step3:
LCM(1, 323) = 323
GCD(1, 323) = ( 1 x 323 ) / 323
= 1 / 323
= 1
So, Greatest Common Divisor of 245, 838, 990, 323 is 1
