Lets's calculate LCM of 886,318
2 | 886, 318 |
443, 159 |
∴ So the LCM of the given numbers is 2 x 443 x 159 = 140874
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 12/140874
Therefore, the GCF of Fractions 408/886,564/318 is 12/140874
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 886,318 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(886,318) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(886,318) x common factors =2 x 1 = 2
LCM(886,318) = ( 886 × 318 ) / 2
LCM(886,318) = 281748 / 2
LCM(886,318) = 140874
