Greatest Common Factor
We found the factors 345,7406 . The biggest common factor number is the GCF number.
So the greatest common factor 345,7406 is 23.
Lets's calculate LCM of 40,615
5 | 40, 615 |
8, 123 |
∴ So the LCM of the given numbers is 5 x 8 x 123 = 4920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/4920
Therefore, the GCF of Fractions 345/40,7406/615 is 23/4920
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 40,615 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,615) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(40,615) x common factors =5 x 1 = 5
LCM(40,615) = ( 40 × 615 ) / 5
LCM(40,615) = 24600 / 5
LCM(40,615) = 4920
