Greatest Common Factor
We found the factors 615,690 . The biggest common factor number is the GCF number.
So the greatest common factor 615,690 is 15.
Lets's calculate LCM of 45,3012
3 | 45, 3012 |
15, 1004 |
∴ So the LCM of the given numbers is 3 x 15 x 1004 = 45180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/45180
Therefore, the GCF of Fractions 615/45,690/3012 is 15/45180
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 45,3012 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,3012) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(45,3012) x common factors =3 x 1 = 3
LCM(45,3012) = ( 45 × 3012 ) / 3
LCM(45,3012) = 135540 / 3
LCM(45,3012) = 45180
