Know Least Common Multiple of fractions 664/686, 445/762 quickly i.e. 147740 the smallest number that is divisible by all numbers by taking the help of LCM of Fractions Calculator.
Least Common Multiple (LCM) of 664/686, 445/762 is 147740.
LCM(664/686, 445/762) = 147740
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given numbers are 664/686,445/762
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 664,445
Least Common Multiple of Numerators i.e. LCM of 664,445 is 295480.
GCF of Denominators means GCF of 686,762 as per the given fractions.
GCF of 686,762 is 2 as it is the largest common factor for these numbers.
Lets's calculate LCM of 664,445
Given numbers has no common factors except 1. So, there LCM is their product i.e 295480
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 664,445 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(664,445) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(664,445) x common factors =1 x 1 = 1
LCM(664,445) = ( 664 × 445 ) / 1
LCM(664,445) = 295480 / 1
LCM(664,445) = 295480
Lets's calculate GCF of 686,762
2 | 686, 762 |
343, 381 |
∴ So the GCF of the given numbers is 2 = 2
Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 295480/2
Therefore the LCM of Fractions 664/686,445/762 is 147740
