Lets's calculate GCF of 717,478
239 | 717, 478 |
3, 2 |
∴ So the GCF of the given numbers is 239 = 239
Now, list down the factors of 717
:1,3,239,717
Now, list down the factors of 478
:1,2,239,478
Greatest Common Factor
We found the factors 717,478 . The biggest common factor number is the GCF number.
So the greatest common factor 717,478 is 239.
Lets's calculate LCM of 290,993
Given numbers has no common factors except 1. So, there LCM is their product i.e 287970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 239/287970
Therefore, the GCF of Fractions 717/290,478/993 is 239/287970
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 290,993 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(290,993) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(290,993) x common factors =1 x 1 = 1
LCM(290,993) = ( 290 × 993 ) / 1
LCM(290,993) = 287970 / 1
LCM(290,993) = 287970
