Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 339/72,641/1580
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 339,641
Greatest Common Factor of Numerators i.e. GCF of 339,641 is 1 .
LCM of Denominators means LCM of 72,1580 as per the given fractions.
LCM of 72,1580 is 28440 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 339,641
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 339
List of positive integer factors of 339 that divides 339 without a remainder.
1,3,113,339
Factors of 641
List of positive integer factors of 641 that divides 641 without a remainder.
1,641
Greatest Common Factor
We found the factors 339,641 . The biggest common factor number is the GCF number.
So the greatest common factor 339,641 is 1.
Lets's calculate LCM of 72,1580
2 | 72, 1580 |
2 | 36, 790 |
18, 395 |
∴ So the LCM of the given numbers is 2 x 2 x 18 x 395 = 28440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28440
Therefore, the GCF of Fractions 339/72,641/1580 is 1/28440
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 72,1580 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,1580) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(72,1580) x common factors =4 x 1 = 4
LCM(72,1580) = ( 72 × 1580 ) / 4
LCM(72,1580) = 113760 / 4
LCM(72,1580) = 28440
