Lets's calculate GCF of 286,143
11 | 286, 143 |
13 | 26, 13 |
2, 1 |
∴ So the GCF of the given numbers is 11 x 13 = 143
Now, list down the factors of 286
:1,2,11,13,22,26,143,286
Now, list down the factors of 143
:1,11,13,143
Greatest Common Factor
We found the factors 286,143 . The biggest common factor number is the GCF number.
So the greatest common factor 286,143 is 143.
Lets's calculate LCM of 39,705
3 | 39, 705 |
13, 235 |
∴ So the LCM of the given numbers is 3 x 13 x 235 = 9165
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 143/9165
Therefore, the GCF of Fractions 286/39,143/705 is 143/9165
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 39,705 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,705) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(39,705) x common factors =3 x 1 = 3
LCM(39,705) = ( 39 × 705 ) / 3
LCM(39,705) = 27495 / 3
LCM(39,705) = 9165
