Greatest Common Factor
We found the factors 912,7836 . The biggest common factor number is the GCF number.
So the greatest common factor 912,7836 is 12.
Lets's calculate LCM of 470,960
2 | 470, 960 |
5 | 235, 480 |
47, 96 |
∴ So the LCM of the given numbers is 2 x 5 x 47 x 96 = 45120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/45120
Therefore, the GCF of Fractions 912/470,7836/960 is 12/45120
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 470,960 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(470,960) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(470,960) x common factors =10 x 1 = 10
LCM(470,960) = ( 470 × 960 ) / 10
LCM(470,960) = 451200 / 10
LCM(470,960) = 45120
