So the greatest common factor 7971,2280 is 3.
Lets's calculate LCM of 86,442
2 | 86, 442 |
43, 221 |
∴ So the LCM of the given numbers is 2 x 43 x 221 = 19006
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/19006
Therefore, the GCF of Fractions 7971/86,2280/442 is 3/19006
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 86,442 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,442) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(86,442) x common factors =2 x 1 = 2
LCM(86,442) = ( 86 × 442 ) / 2
LCM(86,442) = 38012 / 2
LCM(86,442) = 19006
