Greatest Common Factor
We found the factors 3120,7080 . The biggest common factor number is the GCF number.
So the greatest common factor 3120,7080 is 120.
Lets's calculate LCM of 66,944
2 | 66, 944 |
33, 472 |
∴ So the LCM of the given numbers is 2 x 33 x 472 = 31152
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 120/31152
Therefore, the GCF of Fractions 3120/66,7080/944 is 120/31152
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 66,944 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,944) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(66,944) x common factors =2 x 1 = 2
LCM(66,944) = ( 66 × 944 ) / 2
LCM(66,944) = 62304 / 2
LCM(66,944) = 31152
