Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 99/45,78/60,619/88
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 99,78,619
Greatest Common Factor of Numerators i.e. GCF of 99,78,619 is 1 .
LCM of Denominators means LCM of 45,60,88 as per the given fractions.
LCM of 45,60,88 is 3960 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 99,78,619
∴ So GCF of numbers is 1 because of no common factors present between them.

1,3,9,11,33,99
Factors of 78
List of positive integer factors of 78 that divides 78 without a remainder.
1,2,3,6,13,26,39,78
Factors of 619
List of positive integer factors of 619 that divides 619 without a remainder.
1,619
Greatest Common Factor
We found the factors 99,78,619 . The biggest common factor number is the GCF number.
So the greatest common factor 99,78,619 is 1.
Lets's calculate LCM of 45,60,88
2 | 45, 60, 88 |
2 | 45, 30, 44 |
3 | 45, 15, 22 |
5 | 5, 15, 22 |
1, 3, 22 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 1 x 3 x 22 = 3960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3960
Therefore, the GCF of Fractions 99/45,78/60,619/88 is 1/3960
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 45,60,88 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,60,88) = 1
common factors(in case of two or more numbers have common factors) = 60
GCF(45,60,88) x common factors =1 x 60 = 60
LCM(45,60,88) = ( 45 × 60 × 88 ) / 60
LCM(45,60,88) = 237600 / 60
LCM(45,60,88) = 3960
