Know Least Common Multiple of fractions 51/26, 21/82, 357/72 quickly i.e. 357/2 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 51/26, 21/82, 357/72 is 357/2.
LCM(51/26, 21/82, 357/72) = 357/2
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 51/26,21/82,357/72
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 51,21,357
Least Common Multiple of Numerators i.e. LCM of 51,21,357 is 357.
GCF of Denominators means GCF of 26,82,72 as per the given fractions.
GCF of 26,82,72 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 51,21,357
3 | 51, 21, 357 |
7 | 17, 7, 119 |
17 | 17, 1, 17 |
1, 1, 1 |
∴ So the LCM of the given numbers is 3 x 7 x 17 x 1 x 1 x 1 = 357
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 51,21,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,21,357) = 3
common factors(in case of two or more numbers have common factors) = 357
GCF(51,21,357) x common factors =3 x 357 = 1071
LCM(51,21,357) = ( 51 × 21 × 357 ) / 1071
LCM(51,21,357) = 382347 / 1071
LCM(51,21,357) = 357
Lets's calculate GCF of 26,82,72
2 | 26, 82, 72 |
13, 41, 36 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 357/2
Therefore the LCM of Fractions 51/26,21/82,357/72 is 357/2
