Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 6/13,520/12,122/34
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 6,520,122
Greatest Common Factor of Numerators i.e. GCF of 6,520,122 is 2 .
LCM of Denominators means LCM of 13,12,34 as per the given fractions.
LCM of 13,12,34 is 2652 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 6,520,122
2 | 6, 520, 122 |
3, 260, 61 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 6
List of positive integer factors of 6 that divides 6 without a remainder.
1,2,3,6
Factors of 520
List of positive integer factors of 520 that divides 520 without a remainder.
1,2,4,5,8,10,13,20,26,40,52,65,104,130,260,520
Factors of 122
List of positive integer factors of 122 that divides 122 without a remainder.
1,2,61,122
Greatest Common Factor
We found the factors 6,520,122 . The biggest common factor number is the GCF number.
So the greatest common factor 6,520,122 is 2.
Lets's calculate LCM of 13,12,34
2 | 13, 12, 34 |
13, 6, 17 |
∴ So the LCM of the given numbers is 2 x 13 x 6 x 17 = 2652
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2652
Therefore, the GCF of Fractions 6/13,520/12,122/34 is 2/2652
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 13,12,34 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,12,34) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(13,12,34) x common factors =1 x 2 = 2
LCM(13,12,34) = ( 13 × 12 × 34 ) / 2
LCM(13,12,34) = 5304 / 2
LCM(13,12,34) = 2652
