So the greatest common factor 447,684 is 3.
Lets's calculate LCM of 78,7260
2 | 78, 7260 |
3 | 39, 3630 |
13, 1210 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1210 = 94380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/94380
Therefore, the GCF of Fractions 447/78,684/7260 is 3/94380
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 78,7260 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,7260) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(78,7260) x common factors =6 x 1 = 6
LCM(78,7260) = ( 78 × 7260 ) / 6
LCM(78,7260) = 566280 / 6
LCM(78,7260) = 94380
