We found the factors 1389,1102 . The biggest common factor number is the GCF number.
So the greatest common factor 1389,1102 is 1.
Lets's calculate LCM of 585,290
5 | 585, 290 |
117, 58 |
∴ So the LCM of the given numbers is 5 x 117 x 58 = 33930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33930
Therefore, the GCF of Fractions 1389/585,1102/290 is 1/33930
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 585,290 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(585,290) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(585,290) x common factors =5 x 1 = 5
LCM(585,290) = ( 585 × 290 ) / 5
LCM(585,290) = 169650 / 5
LCM(585,290) = 33930
