Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 280/77,674/420
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 280,674
Greatest Common Factor of Numerators i.e. GCF of 280,674 is 2 .
LCM of Denominators means LCM of 77,420 as per the given fractions.
LCM of 77,420 is 4620 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 280,674
2 | 280, 674 |
140, 337 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 674
List of positive integer factors of 674 that divides 674 without a remainder.
1,2,337,674
Greatest Common Factor
We found the factors 280,674 . The biggest common factor number is the GCF number.
So the greatest common factor 280,674 is 2.
Lets's calculate LCM of 77,420
7 | 77, 420 |
11, 60 |
∴ So the LCM of the given numbers is 7 x 11 x 60 = 4620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/4620
Therefore, the GCF of Fractions 280/77,674/420 is 2/4620
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 77,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,420) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(77,420) x common factors =7 x 1 = 7
LCM(77,420) = ( 77 × 420 ) / 7
LCM(77,420) = 32340 / 7
LCM(77,420) = 4620
