So the greatest common factor 845,676 is 169.
Lets's calculate LCM of 12,7834
2 | 12, 7834 |
6, 3917 |
∴ So the LCM of the given numbers is 2 x 6 x 3917 = 47004
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 169/47004
Therefore, the GCF of Fractions 845/12,676/7834 is 169/47004
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 12,7834 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,7834) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(12,7834) x common factors =2 x 1 = 2
LCM(12,7834) = ( 12 × 7834 ) / 2
LCM(12,7834) = 94008 / 2
LCM(12,7834) = 47004
