Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 9/36,101/24,249/42
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 9,101,249
Greatest Common Factor of Numerators i.e. GCF of 9,101,249 is 1 .
LCM of Denominators means LCM of 36,24,42 as per the given fractions.
LCM of 36,24,42 is 504 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 9,101,249
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 9
List of positive integer factors of 9 that divides 9 without a remainder.
1,3,9
Factors of 101
List of positive integer factors of 101 that divides 101 without a remainder.
1,101
Factors of 249
List of positive integer factors of 249 that divides 249 without a remainder.
1,3,83,249
Greatest Common Factor
We found the factors 9,101,249 . The biggest common factor number is the GCF number.
So the greatest common factor 9,101,249 is 1.
Lets's calculate LCM of 36,24,42
2 | 36, 24, 42 |
2 | 18, 12, 21 |
3 | 9, 6, 21 |
3, 2, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 2 x 7 = 504
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/504
Therefore, the GCF of Fractions 9/36,101/24,249/42 is 1/504
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 36,24,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,24,42) = 6
common factors(in case of two or more numbers have common factors) = 12
GCF(36,24,42) x common factors =6 x 12 = 72
LCM(36,24,42) = ( 36 × 24 × 42 ) / 72
LCM(36,24,42) = 36288 / 72
LCM(36,24,42) = 504
