Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 85/654,95/7974
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 85,95
Greatest Common Factor of Numerators i.e. GCF of 85,95 is 5 .
LCM of Denominators means LCM of 654,7974 as per the given fractions.
LCM of 654,7974 is 869166 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 85,95
5 | 85, 95 |
17, 19 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 85
List of positive integer factors of 85 that divides 85 without a remainder.
1,5,17,85
Factors of 95
List of positive integer factors of 95 that divides 95 without a remainder.
1,5,19,95
Greatest Common Factor
We found the factors 85,95 . The biggest common factor number is the GCF number.
So the greatest common factor 85,95 is 5.
Lets's calculate LCM of 654,7974
2 | 654, 7974 |
3 | 327, 3987 |
109, 1329 |
∴ So the LCM of the given numbers is 2 x 3 x 109 x 1329 = 869166
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/869166
Therefore, the GCF of Fractions 85/654,95/7974 is 5/869166
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 654,7974 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(654,7974) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(654,7974) x common factors =6 x 1 = 6
LCM(654,7974) = ( 654 × 7974 ) / 6
LCM(654,7974) = 5214996 / 6
LCM(654,7974) = 869166
