Lets's calculate GCF of 615,723
3 | 615, 723 |
205, 241 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 615
:1,3,5,15,41,123,205,615
Now, list down the factors of 723
:1,3,241,723
Greatest Common Factor
We found the factors 615,723 . The biggest common factor number is the GCF number.
So the greatest common factor 615,723 is 3.
Lets's calculate LCM of 278,412
2 | 278, 412 |
139, 206 |
∴ So the LCM of the given numbers is 2 x 139 x 206 = 57268
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/57268
Therefore, the GCF of Fractions 615/278,723/412 is 3/57268
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 278,412 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(278,412) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(278,412) x common factors =2 x 1 = 2
LCM(278,412) = ( 278 × 412 ) / 2
LCM(278,412) = 114536 / 2
LCM(278,412) = 57268
