So the greatest common factor 423,846 is 423.
Lets's calculate LCM of 846,116
2 | 846, 116 |
423, 58 |
∴ So the LCM of the given numbers is 2 x 423 x 58 = 49068
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 423/49068
Therefore, the GCF of Fractions 423/846,846/116 is 423/49068
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 846,116 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(846,116) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(846,116) x common factors =2 x 1 = 2
LCM(846,116) = ( 846 × 116 ) / 2
LCM(846,116) = 98136 / 2
LCM(846,116) = 49068
