Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 87/678,174/106
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 87,174
Greatest Common Factor of Numerators i.e. GCF of 87,174 is 87 .
LCM of Denominators means LCM of 678,106 as per the given fractions.
LCM of 678,106 is 35934 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 87,174
3 | 87, 174 |
29 | 29, 58 |
1, 2 |
∴ So the GCF of the given numbers is 3 x 29 = 87
Factors of 87

Factors of 174
List of positive integer factors of 174 that divides 174 without a remainder.
1,2,3,6,29,58,87,174
Greatest Common Factor
We found the factors 87,174 . The biggest common factor number is the GCF number.
So the greatest common factor 87,174 is 87.
Lets's calculate LCM of 678,106
2 | 678, 106 |
339, 53 |
∴ So the LCM of the given numbers is 2 x 339 x 53 = 35934
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 87/35934
Therefore, the GCF of Fractions 87/678,174/106 is 87/35934
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 678,106 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(678,106) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(678,106) x common factors =2 x 1 = 2
LCM(678,106) = ( 678 × 106 ) / 2
LCM(678,106) = 71868 / 2
LCM(678,106) = 35934
