Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 129/89,342/247
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 129,342
Greatest Common Factor of Numerators i.e. GCF of 129,342 is 3 .
LCM of Denominators means LCM of 89,247 as per the given fractions.
LCM of 89,247 is 21983 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 129,342
3 | 129, 342 |
43, 114 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 129
List of positive integer factors of 129 that divides 129 without a remainder.
1,3,43,129
Factors of 342
List of positive integer factors of 342 that divides 342 without a remainder.
1,2,3,6,9,18,19,38,57,114,171,342
Greatest Common Factor
We found the factors 129,342 . The biggest common factor number is the GCF number.
So the greatest common factor 129,342 is 3.
Lets's calculate LCM of 89,247
Given numbers has no common factors except 1. So, there LCM is their product i.e 21983
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/21983
Therefore, the GCF of Fractions 129/89,342/247 is 3/21983
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 89,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,247) x common factors =1 x 1 = 1
LCM(89,247) = ( 89 × 247 ) / 1
LCM(89,247) = 21983 / 1
LCM(89,247) = 21983
