So the greatest common factor 1220,8904 is 4.
Lets's calculate LCM of 798,448
2 | 798, 448 |
7 | 399, 224 |
57, 32 |
∴ So the LCM of the given numbers is 2 x 7 x 57 x 32 = 25536
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/25536
Therefore, the GCF of Fractions 1220/798,8904/448 is 4/25536
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 798,448 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(798,448) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(798,448) x common factors =14 x 1 = 14
LCM(798,448) = ( 798 × 448 ) / 14
LCM(798,448) = 357504 / 14
LCM(798,448) = 25536
