Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 76/78,46/39,132/26
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 76,46,132
Greatest Common Factor of Numerators i.e. GCF of 76,46,132 is 2 .
LCM of Denominators means LCM of 78,39,26 as per the given fractions.
LCM of 78,39,26 is 78 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 76,46,132
2 | 76, 46, 132 |
38, 23, 66 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 76
List of positive integer factors of 76 that divides 76 without a remainder.
1,2,4,19,38,76
Factors of 46
List of positive integer factors of 46 that divides 46 without a remainder.
1,2,23,46
Factors of 132
List of positive integer factors of 132 that divides 132 without a remainder.
1,2,3,4,6,11,12,22,33,44,66,132
Greatest Common Factor
We found the factors 76,46,132 . The biggest common factor number is the GCF number.
So the greatest common factor 76,46,132 is 2.
Lets's calculate LCM of 78,39,26
2 | 78, 39, 26 |
3 | 39, 39, 13 |
13 | 13, 13, 13 |
1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 1 x 1 = 78
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/78
Therefore, the GCF of Fractions 76/78,46/39,132/26 is 2/78
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 78,39,26 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,39,26) = 13
common factors(in case of two or more numbers have common factors) = 78
GCF(78,39,26) x common factors =13 x 78 = 1014
LCM(78,39,26) = ( 78 × 39 × 26 ) / 1014
LCM(78,39,26) = 79092 / 1014
LCM(78,39,26) = 78
