Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 43/458,639/764
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 43,639
Greatest Common Factor of Numerators i.e. GCF of 43,639 is 1 .
LCM of Denominators means LCM of 458,764 as per the given fractions.
LCM of 458,764 is 174956 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 43,639
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 43
List of positive integer factors of 43 that divides 43 without a remainder.
1,43
Factors of 639
List of positive integer factors of 639 that divides 639 without a remainder.
1,3,9,71,213,639
Greatest Common Factor
We found the factors 43,639 . The biggest common factor number is the GCF number.
So the greatest common factor 43,639 is 1.
Lets's calculate LCM of 458,764
2 | 458, 764 |
229, 382 |
∴ So the LCM of the given numbers is 2 x 229 x 382 = 174956
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/174956
Therefore, the GCF of Fractions 43/458,639/764 is 1/174956
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 458,764 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(458,764) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(458,764) x common factors =2 x 1 = 2
LCM(458,764) = ( 458 × 764 ) / 2
LCM(458,764) = 349912 / 2
LCM(458,764) = 174956
