So the greatest common factor 855,357 is 3.
Lets's calculate LCM of 202,886
2 | 202, 886 |
101, 443 |
∴ So the LCM of the given numbers is 2 x 101 x 443 = 89486
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/89486
Therefore, the GCF of Fractions 855/202,357/886 is 3/89486
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 202,886 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(202,886) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(202,886) x common factors =2 x 1 = 2
LCM(202,886) = ( 202 × 886 ) / 2
LCM(202,886) = 178972 / 2
LCM(202,886) = 89486
