Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 9/77,51/153,42/575
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 9,51,42
Greatest Common Factor of Numerators i.e. GCF of 9,51,42 is 3 .
LCM of Denominators means LCM of 77,153,575 as per the given fractions.
LCM of 77,153,575 is 6774075 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 9,51,42
3 | 9, 51, 42 |
3, 17, 14 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 9
List of positive integer factors of 9 that divides 9 without a remainder.
1,3,9
Factors of 51
List of positive integer factors of 51 that divides 51 without a remainder.
1,3,17,51
Factors of 42
List of positive integer factors of 42 that divides 42 without a remainder.
1,2,3,6,7,14,21,42
Greatest Common Factor
We found the factors 9,51,42 . The biggest common factor number is the GCF number.
So the greatest common factor 9,51,42 is 3.
Lets's calculate LCM of 77,153,575
Given numbers has no common factors except 1. So, there LCM is their product i.e 6774075
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6774075
Therefore, the GCF of Fractions 9/77,51/153,42/575 is 3/6774075
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 77,153,575 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,153,575) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,153,575) x common factors =1 x 1 = 1
LCM(77,153,575) = ( 77 × 153 × 575 ) / 1
LCM(77,153,575) = 6774075 / 1
LCM(77,153,575) = 6774075
