Know Least Common Multiple of fractions 105/30, 630/76, 741/86 quickly i.e. 77805 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 105/30, 630/76, 741/86 is 77805.
LCM(105/30, 630/76, 741/86) = 77805
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 105/30,630/76,741/86
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 105,630,741
Least Common Multiple of Numerators i.e. LCM of 105,630,741 is 155610.
GCF of Denominators means GCF of 30,76,86 as per the given fractions.
GCF of 30,76,86 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 105,630,741
3 | 105, 630, 741 |
5 | 35, 210, 247 |
7 | 7, 42, 247 |
1, 6, 247 |
∴ So the LCM of the given numbers is 3 x 5 x 7 x 1 x 6 x 247 = 155610
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 105,630,741 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(105,630,741) = 3
common factors(in case of two or more numbers have common factors) = 105
GCF(105,630,741) x common factors =3 x 105 = 315
LCM(105,630,741) = ( 105 × 630 × 741 ) / 315
LCM(105,630,741) = 49017150 / 315
LCM(105,630,741) = 155610
Lets's calculate GCF of 30,76,86
2 | 30, 76, 86 |
15, 38, 43 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 155610/2
Therefore the LCM of Fractions 105/30,630/76,741/86 is 77805
