Know Least Common Multiple of fractions 77/84, 338/26, 638/390 quickly i.e. 377377 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 77/84, 338/26, 638/390 is 377377.
LCM(77/84, 338/26, 638/390) = 377377
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 77/84,338/26,638/390
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 77,338,638
Least Common Multiple of Numerators i.e. LCM of 77,338,638 is 754754.
GCF of Denominators means GCF of 84,26,390 as per the given fractions.
GCF of 84,26,390 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 77,338,638
2 | 77, 338, 638 |
11 | 77, 169, 319 |
7, 169, 29 |
∴ So the LCM of the given numbers is 2 x 11 x 7 x 169 x 29 = 754754
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 77,338,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,338,638) = 1
common factors(in case of two or more numbers have common factors) = 22
GCF(77,338,638) x common factors =1 x 22 = 22
LCM(77,338,638) = ( 77 × 338 × 638 ) / 22
LCM(77,338,638) = 16604588 / 22
LCM(77,338,638) = 754754
Lets's calculate GCF of 84,26,390
2 | 84, 26, 390 |
42, 13, 195 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 754754/2
Therefore the LCM of Fractions 77/84,338/26,638/390 is 377377
