Greatest Common Factor
We found the factors 346,2046 . The biggest common factor number is the GCF number.
So the greatest common factor 346,2046 is 2.
Lets's calculate LCM of 490,690
2 | 490, 690 |
5 | 245, 345 |
49, 69 |
∴ So the LCM of the given numbers is 2 x 5 x 49 x 69 = 33810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/33810
Therefore, the GCF of Fractions 346/490,2046/690 is 2/33810
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 490,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,690) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(490,690) x common factors =10 x 1 = 10
LCM(490,690) = ( 490 × 690 ) / 10
LCM(490,690) = 338100 / 10
LCM(490,690) = 33810
