Know Least Common Multiple of fractions 49/14, 91/64, 63/71, 63/581 quickly i.e. 5733 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 49/14, 91/64, 63/71, 63/581 is 5733.
LCM(49/14, 91/64, 63/71, 63/581) = 5733
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 49/14,91/64,63/71,63/581
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 49,91,63,63
Least Common Multiple of Numerators i.e. LCM of 49,91,63,63 is 5733.
GCF of Denominators means GCF of 14,64,71,581 as per the given fractions.
GCF of 14,64,71,581 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 49,91,63,63
3 | 49, 91, 63, 63 |
3 | 49, 91, 21, 21 |
7 | 49, 91, 7, 7 |
1, 13, 1, 7 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 1 x 13 x 1 x 7 = 5733
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 49,91,63,63 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,91,63,63) = 7
common factors(in case of two or more numbers have common factors) = 441
GCF(49,91,63,63) x common factors =7 x 441 = 3087
LCM(49,91,63,63) = ( 49 × 91 × 63 × 63 ) / 3087
LCM(49,91,63,63) = 17697771 / 3087
LCM(49,91,63,63) = 5733
Lets's calculate GCF of 14,64,71,581
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 5733/1
Therefore the LCM of Fractions 49/14,91/64,63/71,63/581 is 5733
