Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 81/585,61/975
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 81/585,61/975, numerators are 81,61
Denominators are 585,975
The GCF of 81,61 is 1 .
LCM of 585,975 is 2925.
The greatest common factor of 81/585,61/975 = [GCF of 81,61]/[LCM of 585,975]= 1/2925
Therefore, the GCF of 81/585,61/975 is 1/2925.
To find the highest common factor of 81,61, we have to find the factors of both numbers and list the highest common factor.
The factors of 81 are 1, 3, 9, 27, 81
The factors of 61 are 1, 61
The HCF of 81,61 is 1.
Lets's calculate GCF of 81,61
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 585,975
3 | 585, 975 |
5 | 195, 325 |
13 | 39, 65 |
3, 5 |
∴ So the LCM of the given numbers is 3 x 5 x 13 x 3 x 5 = 2925
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2925
Therefore, the GCF of Fractions 81/585,61/975 is 1/2925
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 585,975 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(585,975) = 195
common factors(in case of two or more numbers have common factors) = 1
GCF(585,975) x common factors =195 x 1 = 195
LCM(585,975) = ( 585 × 975 ) / 195
LCM(585,975) = 570375 / 195
LCM(585,975) = 2925
