Know Least Common Multiple of fractions 5642/28, 5640/930 quickly i.e. 7955220 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 5642/28, 5640/930 is 7955220.
LCM(5642/28, 5640/930) = 7955220
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 5642/28,5640/930
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 5642,5640
Least Common Multiple of Numerators i.e. LCM of 5642,5640 is 15910440.
GCF of Denominators means GCF of 28,930 as per the given fractions.
GCF of 28,930 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 5642,5640
2 | 5642, 5640 |
2821, 2820 |
∴ So the LCM of the given numbers is 2 x 2821 x 2820 = 15910440
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 5642,5640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(5642,5640) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(5642,5640) x common factors =2 x 1 = 2
LCM(5642,5640) = ( 5642 × 5640 ) / 2
LCM(5642,5640) = 31820880 / 2
LCM(5642,5640) = 15910440
Lets's calculate GCF of 28,930
2 | 28, 930 |
14, 465 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 15910440/2
Therefore the LCM of Fractions 5642/28,5640/930 is 7955220
