Know Least Common Multiple of fractions 26/48, 90/17, 65/49, 142/72 quickly i.e. 83070 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 26/48, 90/17, 65/49, 142/72 is 83070.
LCM(26/48, 90/17, 65/49, 142/72) = 83070
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 26/48,90/17,65/49,142/72
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 26,90,65,142
Least Common Multiple of Numerators i.e. LCM of 26,90,65,142 is 83070.
GCF of Denominators means GCF of 48,17,49,72 as per the given fractions.
GCF of 48,17,49,72 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 26,90,65,142
2 | 26, 90, 65, 142 |
5 | 13, 45, 65, 71 |
13 | 13, 9, 13, 71 |
1, 9, 1, 71 |
∴ So the LCM of the given numbers is 2 x 5 x 13 x 1 x 9 x 1 x 71 = 83070
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 26,90,65,142 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,90,65,142) = 1
common factors(in case of two or more numbers have common factors) = 260
GCF(26,90,65,142) x common factors =1 x 260 = 260
LCM(26,90,65,142) = ( 26 × 90 × 65 × 142 ) / 260
LCM(26,90,65,142) = 21598200 / 260
LCM(26,90,65,142) = 83070
Lets's calculate GCF of 48,17,49,72
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 83070/1
Therefore the LCM of Fractions 26/48,90/17,65/49,142/72 is 83070
