We found the factors 249,433 . The biggest common factor number is the GCF number.
So the greatest common factor 249,433 is 1.
Lets's calculate LCM of 480,745
5 | 480, 745 |
96, 149 |
∴ So the LCM of the given numbers is 5 x 96 x 149 = 71520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/71520
Therefore, the GCF of Fractions 249/480,433/745 is 1/71520
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 480,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(480,745) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(480,745) x common factors =5 x 1 = 5
LCM(480,745) = ( 480 × 745 ) / 5
LCM(480,745) = 357600 / 5
LCM(480,745) = 71520
