Greatest Common Factor
We found the factors 12,78,945 . The biggest common factor number is the GCF number.
So the greatest common factor 12,78,945 is 3.
Lets's calculate LCM of 15,814,435
3 | 15, 814, 435 |
5 | 5, 814, 145 |
1, 814, 29 |
∴ So the LCM of the given numbers is 3 x 5 x 1 x 814 x 29 = 354090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/354090
Therefore, the GCF of Fractions 12/15,78/814,945/435 is 3/354090
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 15,814,435 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,814,435) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(15,814,435) x common factors =1 x 15 = 15
LCM(15,814,435) = ( 15 × 814 × 435 ) / 15
LCM(15,814,435) = 5311350 / 15
LCM(15,814,435) = 354090
