The HCF of 45,70,115 is 5.
Lets's calculate GCF of 45,70,115
5 | 45, 70, 115 |
9, 14, 23 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 45
:1,3,5,9,15,45
Now, list down the factors of 70
:1,2,5,7,10,14,35,70
Now, list down the factors of 115
:1,5,23,115
Greatest Common Factor
We found the factors 45,70,115 . The biggest common factor number is the GCF number.
So the greatest common factor 45,70,115 is 5.
Lets's calculate LCM of 59,18,34
2 | 59, 18, 34 |
59, 9, 17 |
∴ So the LCM of the given numbers is 2 x 59 x 9 x 17 = 18054
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/18054
Therefore, the GCF of Fractions 45/59,70/18,115/34 is 5/18054
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 59,18,34 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(59,18,34) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(59,18,34) x common factors =1 x 2 = 2
LCM(59,18,34) = ( 59 × 18 × 34 ) / 2
LCM(59,18,34) = 36108 / 2
LCM(59,18,34) = 18054
