Greatest Common Factor
We found the factors 2451,6381 . The biggest common factor number is the GCF number.
So the greatest common factor 2451,6381 is 3.
Lets's calculate LCM of 105,645
3 | 105, 645 |
5 | 35, 215 |
7, 43 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 43 = 4515
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/4515
Therefore, the GCF of Fractions 2451/105,6381/645 is 3/4515
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 105,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(105,645) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(105,645) x common factors =15 x 1 = 15
LCM(105,645) = ( 105 × 645 ) / 15
LCM(105,645) = 67725 / 15
LCM(105,645) = 4515
