Know Least Common Multiple of fractions 36/39, 78/79, 35/14, 40/692 quickly i.e. 32760 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 36/39, 78/79, 35/14, 40/692 is 32760.
LCM(36/39, 78/79, 35/14, 40/692) = 32760
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 36/39,78/79,35/14,40/692
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 36,78,35,40
Least Common Multiple of Numerators i.e. LCM of 36,78,35,40 is 32760.
GCF of Denominators means GCF of 39,79,14,692 as per the given fractions.
GCF of 39,79,14,692 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 36,78,35,40
2 | 36, 78, 35, 40 |
2 | 18, 39, 35, 20 |
3 | 9, 39, 35, 10 |
5 | 3, 13, 35, 10 |
3, 13, 7, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 3 x 13 x 7 x 2 = 32760
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 36,78,35,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,78,35,40) = 1
common factors(in case of two or more numbers have common factors) = 120
GCF(36,78,35,40) x common factors =1 x 120 = 120
LCM(36,78,35,40) = ( 36 × 78 × 35 × 40 ) / 120
LCM(36,78,35,40) = 3931200 / 120
LCM(36,78,35,40) = 32760
Lets's calculate GCF of 39,79,14,692
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 32760/1
Therefore the LCM of Fractions 36/39,78/79,35/14,40/692 is 32760
