Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 82/765,76/4190
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 82,76
Greatest Common Factor of Numerators i.e. GCF of 82,76 is 2 .
LCM of Denominators means LCM of 765,4190 as per the given fractions.
LCM of 765,4190 is 641070 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 82,76
2 | 82, 76 |
41, 38 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 82
List of positive integer factors of 82 that divides 82 without a remainder.
1,2,41,82
Factors of 76
List of positive integer factors of 76 that divides 76 without a remainder.
1,2,4,19,38,76
Greatest Common Factor
We found the factors 82,76 . The biggest common factor number is the GCF number.
So the greatest common factor 82,76 is 2.
Lets's calculate LCM of 765,4190
5 | 765, 4190 |
153, 838 |
∴ So the LCM of the given numbers is 5 x 153 x 838 = 641070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/641070
Therefore, the GCF of Fractions 82/765,76/4190 is 2/641070
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 765,4190 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(765,4190) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(765,4190) x common factors =5 x 1 = 5
LCM(765,4190) = ( 765 × 4190 ) / 5
LCM(765,4190) = 3205350 / 5
LCM(765,4190) = 641070
