Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 54/11,87/86,172/140
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 54,87,172
Greatest Common Factor of Numerators i.e. GCF of 54,87,172 is 1 .
LCM of Denominators means LCM of 11,86,140 as per the given fractions.
LCM of 11,86,140 is 66220 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 54,87,172
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 54
List of positive integer factors of 54 that divides 54 without a remainder.
1,2,3,6,9,18,27,54
Factors of 87
List of positive integer factors of 87 that divides 87 without a remainder.
1,3,29,87
Factors of 172
List of positive integer factors of 172 that divides 172 without a remainder.
1,2,4,43,86,172
Greatest Common Factor
We found the factors 54,87,172 . The biggest common factor number is the GCF number.
So the greatest common factor 54,87,172 is 1.
Lets's calculate LCM of 11,86,140
2 | 11, 86, 140 |
11, 43, 70 |
∴ So the LCM of the given numbers is 2 x 11 x 43 x 70 = 66220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/66220
Therefore, the GCF of Fractions 54/11,87/86,172/140 is 1/66220
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 11,86,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,86,140) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(11,86,140) x common factors =1 x 2 = 2
LCM(11,86,140) = ( 11 × 86 × 140 ) / 2
LCM(11,86,140) = 132440 / 2
LCM(11,86,140) = 66220
