So the greatest common factor 450,318 is 6.
Lets's calculate LCM of 861,392
7 | 861, 392 |
123, 56 |
∴ So the LCM of the given numbers is 7 x 123 x 56 = 48216
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/48216
Therefore, the GCF of Fractions 450/861,318/392 is 6/48216
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 861,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(861,392) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(861,392) x common factors =7 x 1 = 7
LCM(861,392) = ( 861 × 392 ) / 7
LCM(861,392) = 337512 / 7
LCM(861,392) = 48216
