Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 55/51,15/24,117/688
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 55,15,117
Greatest Common Factor of Numerators i.e. GCF of 55,15,117 is 1 .
LCM of Denominators means LCM of 51,24,688 as per the given fractions.
LCM of 51,24,688 is 35088 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 55,15,117
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 55

1,5,11,55
Factors of 15
List of positive integer factors of 15 that divides 15 without a remainder.
1,3,5,15
Factors of 117
List of positive integer factors of 117 that divides 117 without a remainder.
1,3,9,13,39,117
Greatest Common Factor
We found the factors 55,15,117 . The biggest common factor number is the GCF number.
So the greatest common factor 55,15,117 is 1.
Lets's calculate LCM of 51,24,688
2 | 51, 24, 688 |
2 | 51, 12, 344 |
2 | 51, 6, 172 |
3 | 51, 3, 86 |
17, 1, 86 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 17 x 1 x 86 = 35088
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/35088
Therefore, the GCF of Fractions 55/51,15/24,117/688 is 1/35088
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 51,24,688 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,24,688) = 1
common factors(in case of two or more numbers have common factors) = 24
GCF(51,24,688) x common factors =1 x 24 = 24
LCM(51,24,688) = ( 51 × 24 × 688 ) / 24
LCM(51,24,688) = 842112 / 24
LCM(51,24,688) = 35088
