Greatest Common Factor
We found the factors 13,15,231 . The biggest common factor number is the GCF number.
So the greatest common factor 13,15,231 is 1.
Lets's calculate LCM of 119,928,294
2 | 119, 928, 294 |
7 | 119, 464, 147 |
17, 464, 21 |
∴ So the LCM of the given numbers is 2 x 7 x 17 x 464 x 21 = 2319072
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2319072
Therefore, the GCF of Fractions 13/119,15/928,231/294 is 1/2319072
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 119,928,294 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(119,928,294) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(119,928,294) x common factors =1 x 14 = 14
LCM(119,928,294) = ( 119 × 928 × 294 ) / 14
LCM(119,928,294) = 32467008 / 14
LCM(119,928,294) = 2319072
