Lets's calculate LCM of 480,7629
3 | 480, 7629 |
160, 2543 |
∴ So the LCM of the given numbers is 3 x 160 x 2543 = 1220640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1220640
Therefore, the GCF of Fractions 18/480,4087/7629 is 1/1220640
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 480,7629 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(480,7629) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(480,7629) x common factors =3 x 1 = 3
LCM(480,7629) = ( 480 × 7629 ) / 3
LCM(480,7629) = 3661920 / 3
LCM(480,7629) = 1220640
