Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 31/91,34/34,631/78
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 31,34,631
Greatest Common Factor of Numerators i.e. GCF of 31,34,631 is 1 .
LCM of Denominators means LCM of 91,34,78 as per the given fractions.
LCM of 91,34,78 is 9282 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 31,34,631
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 31
List of positive integer factors of 31 that divides 31 without a remainder.
1,31
Factors of 34
List of positive integer factors of 34 that divides 34 without a remainder.
1,2,17,34
Factors of 631
List of positive integer factors of 631 that divides 631 without a remainder.
1,631
Greatest Common Factor
We found the factors 31,34,631 . The biggest common factor number is the GCF number.
So the greatest common factor 31,34,631 is 1.
Lets's calculate LCM of 91,34,78
2 | 91, 34, 78 |
13 | 91, 17, 39 |
7, 17, 3 |
∴ So the LCM of the given numbers is 2 x 13 x 7 x 17 x 3 = 9282
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9282
Therefore, the GCF of Fractions 31/91,34/34,631/78 is 1/9282
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 91,34,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,34,78) = 1
common factors(in case of two or more numbers have common factors) = 26
GCF(91,34,78) x common factors =1 x 26 = 26
LCM(91,34,78) = ( 91 × 34 × 78 ) / 26
LCM(91,34,78) = 241332 / 26
LCM(91,34,78) = 9282
