Lets's calculate LCM of 913,825
11 | 913, 825 |
83, 75 |
∴ So the LCM of the given numbers is 11 x 83 x 75 = 68475
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/68475
Therefore, the GCF of Fractions 756/913,6861/825 is 3/68475
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 913,825 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(913,825) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(913,825) x common factors =11 x 1 = 11
LCM(913,825) = ( 913 × 825 ) / 11
LCM(913,825) = 753225 / 11
LCM(913,825) = 68475
