Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 6/42,522/12,291/69
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 6,522,291
Greatest Common Factor of Numerators i.e. GCF of 6,522,291 is 3 .
LCM of Denominators means LCM of 42,12,69 as per the given fractions.
LCM of 42,12,69 is 1932 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 6,522,291
3 | 6, 522, 291 |
2, 174, 97 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 6
List of positive integer factors of 6 that divides 6 without a remainder.
1,2,3,6
Factors of 522
List of positive integer factors of 522 that divides 522 without a remainder.
1,2,3,6,9,18,29,58,87,174,261,522
Factors of 291
List of positive integer factors of 291 that divides 291 without a remainder.
1,3,97,291
Greatest Common Factor
We found the factors 6,522,291 . The biggest common factor number is the GCF number.
So the greatest common factor 6,522,291 is 3.
Lets's calculate LCM of 42,12,69
2 | 42, 12, 69 |
3 | 21, 6, 69 |
7, 2, 23 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 2 x 23 = 1932
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1932
Therefore, the GCF of Fractions 6/42,522/12,291/69 is 3/1932
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 42,12,69 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,12,69) = 3
common factors(in case of two or more numbers have common factors) = 6
GCF(42,12,69) x common factors =3 x 6 = 18
LCM(42,12,69) = ( 42 × 12 × 69 ) / 18
LCM(42,12,69) = 34776 / 18
LCM(42,12,69) = 1932
