Lets's calculate LCM of 45,828
3 | 45, 828 |
3 | 15, 276 |
5, 92 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 92 = 4140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/4140
Therefore, the GCF of Fractions 7659/45,4738/828 is 23/4140
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 45,828 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,828) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(45,828) x common factors =9 x 1 = 9
LCM(45,828) = ( 45 × 828 ) / 9
LCM(45,828) = 37260 / 9
LCM(45,828) = 4140
