Least Common Multiple (LCM) of 91/63, 20/66, 49/79 is 12740.
LCM(91/63, 20/66, 49/79) = 12740
LCM of 91/63, 20/66, 49/79
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 91/63,20/66,49/79
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 91,20,49
Least Common Multiple of Numerators i.e. LCM of 91,20,49 is 12740.
GCF of Denominators means GCF of 63,66,79 as per the given fractions.
GCF of 63,66,79 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 91,20,49
LCM of Fractions 91/63,20/66,49/79 is 12740
| 7 | 91, 20, 49 |
| 13, 20, 7 |
∴ So the LCM of the given numbers is 7 x 13 x 20 x 7 = 12740
Least Common Multiple of 91,20,49 with GCF Formula
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 91,20,49 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,20,49) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(91,20,49) x common factors =1 x 7 = 7
LCM(91,20,49) = ( 91 × 20 × 49 ) / 7
LCM(91,20,49) = 89180 / 7
LCM(91,20,49) = 12740
Lets's calculate GCF of 63,66,79
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 12740/1
Therefore the LCM of Fractions 91/63,20/66,49/79 is 12740
