Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 531/616,801/840
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 531,801
Greatest Common Factor of Numerators i.e. GCF of 531,801 is 9 .
LCM of Denominators means LCM of 616,840 as per the given fractions.
LCM of 616,840 is 9240 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 531,801
3 | 531, 801 |
3 | 177, 267 |
59, 89 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Factors of 531
List of positive integer factors of 531 that divides 531 without a remainder.
1,3,9,59,177,531
Factors of 801
List of positive integer factors of 801 that divides 801 without a remainder.
1,3,9,89,267,801
Greatest Common Factor
We found the factors 531,801 . The biggest common factor number is the GCF number.
So the greatest common factor 531,801 is 9.
Lets's calculate LCM of 616,840
2 | 616, 840 |
2 | 308, 420 |
2 | 154, 210 |
7 | 77, 105 |
11, 15 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 11 x 15 = 9240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/9240
Therefore, the GCF of Fractions 531/616,801/840 is 9/9240
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 616,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(616,840) = 56
common factors(in case of two or more numbers have common factors) = 1
GCF(616,840) x common factors =56 x 1 = 56
LCM(616,840) = ( 616 × 840 ) / 56
LCM(616,840) = 517440 / 56
LCM(616,840) = 9240
