Know Least Common Multiple of fractions 69/65, 80/40, 56/36, 98/407 quickly i.e. 270480 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 69/65, 80/40, 56/36, 98/407 is 270480.
LCM(69/65, 80/40, 56/36, 98/407) = 270480
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 69/65,80/40,56/36,98/407
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 69,80,56,98
Least Common Multiple of Numerators i.e. LCM of 69,80,56,98 is 270480.
GCF of Denominators means GCF of 65,40,36,407 as per the given fractions.
GCF of 65,40,36,407 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 69,80,56,98
2 | 69, 80, 56, 98 |
2 | 69, 40, 28, 49 |
2 | 69, 20, 14, 49 |
7 | 69, 10, 7, 49 |
69, 10, 1, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 69 x 10 x 1 x 7 = 270480
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 69,80,56,98 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,80,56,98) = 1
common factors(in case of two or more numbers have common factors) = 112
GCF(69,80,56,98) x common factors =1 x 112 = 112
LCM(69,80,56,98) = ( 69 × 80 × 56 × 98 ) / 112
LCM(69,80,56,98) = 30293760 / 112
LCM(69,80,56,98) = 270480
Lets's calculate GCF of 65,40,36,407
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 270480/1
Therefore the LCM of Fractions 69/65,80/40,56/36,98/407 is 270480
