Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 142/247,7181/361
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 142,7181
Greatest Common Factor of Numerators i.e. GCF of 142,7181 is 1 .
LCM of Denominators means LCM of 247,361 as per the given fractions.
LCM of 247,361 is 4693 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 142,7181
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 142
List of positive integer factors of 142 that divides 142 without a remainder.
1,2,71,142
Factors of 7181
List of positive integer factors of 7181 that divides 7181 without a remainder.
1,43,167,7181
Greatest Common Factor
We found the factors 142,7181 . The biggest common factor number is the GCF number.
So the greatest common factor 142,7181 is 1.
Lets's calculate LCM of 247,361
19 | 247, 361 |
13, 19 |
∴ So the LCM of the given numbers is 19 x 13 x 19 = 4693
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4693
Therefore, the GCF of Fractions 142/247,7181/361 is 1/4693
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 247,361 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(247,361) = 19
common factors(in case of two or more numbers have common factors) = 1
GCF(247,361) x common factors =19 x 1 = 19
LCM(247,361) = ( 247 × 361 ) / 19
LCM(247,361) = 89167 / 19
LCM(247,361) = 4693
