Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 805/164,721/156
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 805,721
Greatest Common Factor of Numerators i.e. GCF of 805,721 is 7 .
LCM of Denominators means LCM of 164,156 as per the given fractions.
LCM of 164,156 is 6396 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 805,721
7 | 805, 721 |
115, 103 |
∴ So the GCF of the given numbers is 7 = 7

1,7,103,721
Greatest Common Factor
We found the factors 805,721 . The biggest common factor number is the GCF number.
So the greatest common factor 805,721 is 7.
Lets's calculate LCM of 164,156
2 | 164, 156 |
2 | 82, 78 |
41, 39 |
∴ So the LCM of the given numbers is 2 x 2 x 41 x 39 = 6396
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/6396
Therefore, the GCF of Fractions 805/164,721/156 is 7/6396
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 164,156 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(164,156) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(164,156) x common factors =4 x 1 = 4
LCM(164,156) = ( 164 × 156 ) / 4
LCM(164,156) = 25584 / 4
LCM(164,156) = 6396
