Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 155/15,670/143
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 155,670
Greatest Common Factor of Numerators i.e. GCF of 155,670 is 5 .
LCM of Denominators means LCM of 15,143 as per the given fractions.
LCM of 15,143 is 2145 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 155,670
5 | 155, 670 |
31, 134 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 155
List of positive integer factors of 155 that divides 155 without a remainder.
1,5,31,155
Factors of 670
List of positive integer factors of 670 that divides 670 without a remainder.
1,2,5,10,67,134,335,670
Greatest Common Factor
We found the factors 155,670 . The biggest common factor number is the GCF number.
So the greatest common factor 155,670 is 5.
Lets's calculate LCM of 15,143
Given numbers has no common factors except 1. So, there LCM is their product i.e 2145
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/2145
Therefore, the GCF of Fractions 155/15,670/143 is 5/2145
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 15,143 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,143) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(15,143) x common factors =1 x 1 = 1
LCM(15,143) = ( 15 × 143 ) / 1
LCM(15,143) = 2145 / 1
LCM(15,143) = 2145
Here are some samples of GCF of Fractions calculations.
