So the greatest common factor 305,3978 is 1.
Lets's calculate LCM of 450,948
2 | 450, 948 |
3 | 225, 474 |
75, 158 |
∴ So the LCM of the given numbers is 2 x 3 x 75 x 158 = 71100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/71100
Therefore, the GCF of Fractions 305/450,3978/948 is 1/71100
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 450,948 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(450,948) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(450,948) x common factors =6 x 1 = 6
LCM(450,948) = ( 450 × 948 ) / 6
LCM(450,948) = 426600 / 6
LCM(450,948) = 71100
