Know Least Common Multiple of fractions 638/34, 691/7090 quickly i.e. 220429 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 638/34, 691/7090 is 220429.
LCM(638/34, 691/7090) = 220429
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 638/34,691/7090
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 638,691
Least Common Multiple of Numerators i.e. LCM of 638,691 is 440858.
GCF of Denominators means GCF of 34,7090 as per the given fractions.
GCF of 34,7090 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 638,691
Given numbers has no common factors except 1. So, there LCM is their product i.e 440858
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 638,691 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(638,691) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(638,691) x common factors =1 x 1 = 1
LCM(638,691) = ( 638 × 691 ) / 1
LCM(638,691) = 440858 / 1
LCM(638,691) = 440858
Lets's calculate GCF of 34,7090
2 | 34, 7090 |
17, 3545 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 440858/2
Therefore the LCM of Fractions 638/34,691/7090 is 220429
