Know Least Common Multiple of fractions 13/80, 84/88, 49/86, 78/374 quickly i.e. 3822 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 13/80, 84/88, 49/86, 78/374 is 3822.
LCM(13/80, 84/88, 49/86, 78/374) = 3822
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 13/80,84/88,49/86,78/374
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 13,84,49,78
Least Common Multiple of Numerators i.e. LCM of 13,84,49,78 is 7644.
GCF of Denominators means GCF of 80,88,86,374 as per the given fractions.
GCF of 80,88,86,374 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 13,84,49,78
2 | 13, 84, 49, 78 |
3 | 13, 42, 49, 39 |
7 | 13, 14, 49, 13 |
13 | 13, 2, 7, 13 |
1, 2, 7, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 13 x 1 x 2 x 7 x 1 = 7644
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 13,84,49,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,84,49,78) = 1
common factors(in case of two or more numbers have common factors) = 546
GCF(13,84,49,78) x common factors =1 x 546 = 546
LCM(13,84,49,78) = ( 13 × 84 × 49 × 78 ) / 546
LCM(13,84,49,78) = 4173624 / 546
LCM(13,84,49,78) = 7644
Lets's calculate GCF of 80,88,86,374
2 | 80, 88, 86, 374 |
40, 44, 43, 187 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 7644/2
Therefore the LCM of Fractions 13/80,84/88,49/86,78/374 is 3822
