Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 877/840,278/657
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 877,278
Greatest Common Factor of Numerators i.e. GCF of 877,278 is 1 .
LCM of Denominators means LCM of 840,657 as per the given fractions.
LCM of 840,657 is 183960 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 877,278
∴ So GCF of numbers is 1 because of no common factors present between them.

1,877
Factors of 278
List of positive integer factors of 278 that divides 278 without a remainder.
1,2,139,278
Greatest Common Factor
We found the factors 877,278 . The biggest common factor number is the GCF number.
So the greatest common factor 877,278 is 1.
Lets's calculate LCM of 840,657
3 | 840, 657 |
280, 219 |
∴ So the LCM of the given numbers is 3 x 280 x 219 = 183960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/183960
Therefore, the GCF of Fractions 877/840,278/657 is 1/183960
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 840,657 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,657) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(840,657) x common factors =3 x 1 = 3
LCM(840,657) = ( 840 × 657 ) / 3
LCM(840,657) = 551880 / 3
LCM(840,657) = 183960
