3 | 315, 117 |
3 | 105, 39 |
35, 13 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Now, list down the factors of 315
:1,3,5,7,9,15,21,35,45,63,105,315
Now, list down the factors of 117
:1,3,9,13,39,117
Greatest Common Factor
We found the factors 315,117 . The biggest common factor number is the GCF number.
So the greatest common factor 315,117 is 9.
Lets's calculate LCM of 141,270
3 | 141, 270 |
47, 90 |
∴ So the LCM of the given numbers is 3 x 47 x 90 = 12690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/12690
Therefore, the GCF of Fractions 315/141,117/270 is 9/12690
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 141,270 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(141,270) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(141,270) x common factors =3 x 1 = 3
LCM(141,270) = ( 141 × 270 ) / 3
LCM(141,270) = 38070 / 3
LCM(141,270) = 12690
