Lets's calculate LCM of 115,645
5 | 115, 645 |
23, 129 |
∴ So the LCM of the given numbers is 5 x 23 x 129 = 14835
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/14835
Therefore, the GCF of Fractions 586/115,390/645 is 2/14835
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 115,645 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(115,645) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(115,645) x common factors =5 x 1 = 5
LCM(115,645) = ( 115 × 645 ) / 5
LCM(115,645) = 74175 / 5
LCM(115,645) = 14835
