Now, list down the factors of 18
:1,2,3,6,9,18
Now, list down the factors of 496
:1,2,4,8,16,31,62,124,248,496
Greatest Common Factor
We found the factors 81,18,496 . The biggest common factor number is the GCF number.
So the greatest common factor 81,18,496 is 1.
Lets's calculate LCM of 29,15,609
3 | 29, 15, 609 |
29 | 29, 5, 203 |
1, 5, 7 |
∴ So the LCM of the given numbers is 3 x 29 x 1 x 5 x 7 = 3045
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3045
Therefore, the GCF of Fractions 81/29,18/15,496/609 is 1/3045
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 29,15,609 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,15,609) = 1
common factors(in case of two or more numbers have common factors) = 87
GCF(29,15,609) x common factors =1 x 87 = 87
LCM(29,15,609) = ( 29 × 15 × 609 ) / 87
LCM(29,15,609) = 264915 / 87
LCM(29,15,609) = 3045
