Lets's calculate LCM of 832,8076
2 | 832, 8076 |
2 | 416, 4038 |
208, 2019 |
∴ So the LCM of the given numbers is 2 x 2 x 208 x 2019 = 1679808
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1679808
Therefore, the GCF of Fractions 1215/832,3430/8076 is 5/1679808
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 832,8076 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(832,8076) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(832,8076) x common factors =4 x 1 = 4
LCM(832,8076) = ( 832 × 8076 ) / 4
LCM(832,8076) = 6719232 / 4
LCM(832,8076) = 1679808
