Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 251/27,411/41,643/27
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 251,411,643
Greatest Common Factor of Numerators i.e. GCF of 251,411,643 is 1 .
LCM of Denominators means LCM of 27,41,27 as per the given fractions.
LCM of 27,41,27 is 1107 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 251,411,643
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 251
List of positive integer factors of 251 that divides 251 without a remainder.
1,251
Factors of 411
List of positive integer factors of 411 that divides 411 without a remainder.
1,3,137,411
Factors of 643
List of positive integer factors of 643 that divides 643 without a remainder.
1,643
Greatest Common Factor
We found the factors 251,411,643 . The biggest common factor number is the GCF number.
So the greatest common factor 251,411,643 is 1.
Lets's calculate LCM of 27,41,27
3 | 27, 41, 27 |
3 | 9, 41, 9 |
3 | 3, 41, 3 |
1, 41, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 1 x 41 x 1 = 1107
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1107
Therefore, the GCF of Fractions 251/27,411/41,643/27 is 1/1107
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 27,41,27 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,41,27) = 1
common factors(in case of two or more numbers have common factors) = 27
GCF(27,41,27) x common factors =1 x 27 = 27
LCM(27,41,27) = ( 27 × 41 × 27 ) / 27
LCM(27,41,27) = 29889 / 27
LCM(27,41,27) = 1107
