Know Least Common Multiple of fractions 56/55, 55/56, 90/51, 63/867 quickly i.e. 27720 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 56/55, 55/56, 90/51, 63/867 is 27720.
LCM(56/55, 55/56, 90/51, 63/867) = 27720
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 56/55,55/56,90/51,63/867
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 56,55,90,63
Least Common Multiple of Numerators i.e. LCM of 56,55,90,63 is 27720.
GCF of Denominators means GCF of 55,56,51,867 as per the given fractions.
GCF of 55,56,51,867 is 1 as it is the largest common factor for these numbers.
Lets's calculate LCM of 56,55,90,63
2 | 56, 55, 90, 63 |
3 | 28, 55, 45, 63 |
3 | 28, 55, 15, 21 |
5 | 28, 55, 5, 7 |
7 | 28, 11, 1, 7 |
4, 11, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 7 x 4 x 11 x 1 x 1 = 27720
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 56,55,90,63 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,55,90,63) = 1
common factors(in case of two or more numbers have common factors) = 630
GCF(56,55,90,63) x common factors =1 x 630 = 630
LCM(56,55,90,63) = ( 56 × 55 × 90 × 63 ) / 630
LCM(56,55,90,63) = 17463600 / 630
LCM(56,55,90,63) = 27720
Lets's calculate GCF of 55,56,51,867
∴ So GCF of numbers is 1 because of no common factors present between them.
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 27720/1
Therefore the LCM of Fractions 56/55,55/56,90/51,63/867 is 27720
