Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 83/91,89/53,251/861
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 83,89,251
Greatest Common Factor of Numerators i.e. GCF of 83,89,251 is 1 .
LCM of Denominators means LCM of 91,53,861 as per the given fractions.
LCM of 91,53,861 is 593229 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 83,89,251
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 83

1,89
Factors of 251
List of positive integer factors of 251 that divides 251 without a remainder.
1,251
Greatest Common Factor
We found the factors 83,89,251 . The biggest common factor number is the GCF number.
So the greatest common factor 83,89,251 is 1.
Lets's calculate LCM of 91,53,861
7 | 91, 53, 861 |
13, 53, 123 |
∴ So the LCM of the given numbers is 7 x 13 x 53 x 123 = 593229
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/593229
Therefore, the GCF of Fractions 83/91,89/53,251/861 is 1/593229
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 91,53,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,53,861) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(91,53,861) x common factors =1 x 7 = 7
LCM(91,53,861) = ( 91 × 53 × 861 ) / 7
LCM(91,53,861) = 4152603 / 7
LCM(91,53,861) = 593229
