So the greatest common factor 812,715 is 1.
Lets's calculate LCM of 82,864
2 | 82, 864 |
41, 432 |
∴ So the LCM of the given numbers is 2 x 41 x 432 = 35424
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/35424
Therefore, the GCF of Fractions 812/82,715/864 is 1/35424
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 82,864 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(82,864) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(82,864) x common factors =2 x 1 = 2
LCM(82,864) = ( 82 × 864 ) / 2
LCM(82,864) = 70848 / 2
LCM(82,864) = 35424
