Know Least Common Multiple of fractions 40/745, 74/115 quickly i.e. 296 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 40/745, 74/115 is 296.
LCM(40/745, 74/115) = 296
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 40/745,74/115
Formula to find LCM of Fractions is
LCM = LCM of Numerators/GCF of Denominators
As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators
In the given fractions LCM of Numerators means LCM of 40,74
Least Common Multiple of Numerators i.e. LCM of 40,74 is 1480.
GCF of Denominators means GCF of 745,115 as per the given fractions.
GCF of 745,115 is 5 as it is the largest common factor for these numbers.
Lets's calculate LCM of 40,74
2 | 40, 74 |
20, 37 |
∴ So the LCM of the given numbers is 2 x 20 x 37 = 1480
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 40,74 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,74) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(40,74) x common factors =2 x 1 = 2
LCM(40,74) = ( 40 × 74 ) / 2
LCM(40,74) = 2960 / 2
LCM(40,74) = 1480
Lets's calculate GCF of 745,115
5 | 745, 115 |
149, 23 |
∴ So the GCF of the given numbers is 5 = 5
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1480/5
Therefore the LCM of Fractions 40/745,74/115 is 296
