Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 68/992,77/268
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 68,77
Greatest Common Factor of Numerators i.e. GCF of 68,77 is 1 .
LCM of Denominators means LCM of 992,268 as per the given fractions.
LCM of 992,268 is 66464 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 68,77
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 68
List of positive integer factors of 68 that divides 68 without a remainder.
1,2,4,17,34,68
Factors of 77
List of positive integer factors of 77 that divides 77 without a remainder.
1,7,11,77
Greatest Common Factor
We found the factors 68,77 . The biggest common factor number is the GCF number.
So the greatest common factor 68,77 is 1.
Lets's calculate LCM of 992,268
2 | 992, 268 |
2 | 496, 134 |
248, 67 |
∴ So the LCM of the given numbers is 2 x 2 x 248 x 67 = 66464
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/66464
Therefore, the GCF of Fractions 68/992,77/268 is 1/66464
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 992,268 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(992,268) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(992,268) x common factors =4 x 1 = 4
LCM(992,268) = ( 992 × 268 ) / 4
LCM(992,268) = 265856 / 4
LCM(992,268) = 66464
