Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 86/14,79/54,712/49
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 86,79,712
Greatest Common Factor of Numerators i.e. GCF of 86,79,712 is 1 .
LCM of Denominators means LCM of 14,54,49 as per the given fractions.
LCM of 14,54,49 is 2646 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 86,79,712
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 86

1,79
Factors of 712
List of positive integer factors of 712 that divides 712 without a remainder.
1,2,4,8,89,178,356,712
Greatest Common Factor
We found the factors 86,79,712 . The biggest common factor number is the GCF number.
So the greatest common factor 86,79,712 is 1.
Lets's calculate LCM of 14,54,49
2 | 14, 54, 49 |
7 | 7, 27, 49 |
1, 27, 7 |
∴ So the LCM of the given numbers is 2 x 7 x 1 x 27 x 7 = 2646
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2646
Therefore, the GCF of Fractions 86/14,79/54,712/49 is 1/2646
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 14,54,49 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,54,49) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(14,54,49) x common factors =1 x 14 = 14
LCM(14,54,49) = ( 14 × 54 × 49 ) / 14
LCM(14,54,49) = 37044 / 14
LCM(14,54,49) = 2646
