Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 343/905,214/745
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 343,214
Greatest Common Factor of Numerators i.e. GCF of 343,214 is 1 .
LCM of Denominators means LCM of 905,745 as per the given fractions.
LCM of 905,745 is 134845 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 343,214
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 343
List of positive integer factors of 343 that divides 343 without a remainder.
1,7,49,343
Factors of 214
List of positive integer factors of 214 that divides 214 without a remainder.
1,2,107,214
Greatest Common Factor
We found the factors 343,214 . The biggest common factor number is the GCF number.
So the greatest common factor 343,214 is 1.
Lets's calculate LCM of 905,745
5 | 905, 745 |
181, 149 |
∴ So the LCM of the given numbers is 5 x 181 x 149 = 134845
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/134845
Therefore, the GCF of Fractions 343/905,214/745 is 1/134845
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 905,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(905,745) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(905,745) x common factors =5 x 1 = 5
LCM(905,745) = ( 905 × 745 ) / 5
LCM(905,745) = 674225 / 5
LCM(905,745) = 134845
