Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 477/862,531/920
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 477,531
Greatest Common Factor of Numerators i.e. GCF of 477,531 is 9 .
LCM of Denominators means LCM of 862,920 as per the given fractions.
LCM of 862,920 is 396520 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 477,531
3 | 477, 531 |
3 | 159, 177 |
53, 59 |
∴ So the GCF of the given numbers is 3 x 3 = 9

1,3,9,59,177,531
Greatest Common Factor
We found the factors 477,531 . The biggest common factor number is the GCF number.
So the greatest common factor 477,531 is 9.
Lets's calculate LCM of 862,920
2 | 862, 920 |
431, 460 |
∴ So the LCM of the given numbers is 2 x 431 x 460 = 396520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/396520
Therefore, the GCF of Fractions 477/862,531/920 is 9/396520
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 862,920 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(862,920) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(862,920) x common factors =2 x 1 = 2
LCM(862,920) = ( 862 × 920 ) / 2
LCM(862,920) = 793040 / 2
LCM(862,920) = 396520
