Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 89/255,623/783
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 89,623
Greatest Common Factor of Numerators i.e. GCF of 89,623 is 89 .
LCM of Denominators means LCM of 255,783 as per the given fractions.
LCM of 255,783 is 66555 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 89,623
89 | 89, 623 |
1, 7 |
∴ So the GCF of the given numbers is 89 = 89
Factors of 89
List of positive integer factors of 89 that divides 89 without a remainder.
1,89
Factors of 623
List of positive integer factors of 623 that divides 623 without a remainder.
1,7,89,623
Greatest Common Factor
We found the factors 89,623 . The biggest common factor number is the GCF number.
So the greatest common factor 89,623 is 89.
Lets's calculate LCM of 255,783
3 | 255, 783 |
85, 261 |
∴ So the LCM of the given numbers is 3 x 85 x 261 = 66555
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 89/66555
Therefore, the GCF of Fractions 89/255,623/783 is 89/66555
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 255,783 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(255,783) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(255,783) x common factors =3 x 1 = 3
LCM(255,783) = ( 255 × 783 ) / 3
LCM(255,783) = 199665 / 3
LCM(255,783) = 66555
