Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 6/60,142/34,644/31
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 6,142,644
Greatest Common Factor of Numerators i.e. GCF of 6,142,644 is 2 .
LCM of Denominators means LCM of 60,34,31 as per the given fractions.
LCM of 60,34,31 is 31620 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 6,142,644
2 | 6, 142, 644 |
3, 71, 322 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 6

1,2,71,142
Factors of 644
List of positive integer factors of 644 that divides 644 without a remainder.
1,2,4,7,14,23,28,46,92,161,322,644
Greatest Common Factor
We found the factors 6,142,644 . The biggest common factor number is the GCF number.
So the greatest common factor 6,142,644 is 2.
Lets's calculate LCM of 60,34,31
2 | 60, 34, 31 |
30, 17, 31 |
∴ So the LCM of the given numbers is 2 x 30 x 17 x 31 = 31620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/31620
Therefore, the GCF of Fractions 6/60,142/34,644/31 is 2/31620
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 60,34,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(60,34,31) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(60,34,31) x common factors =1 x 2 = 2
LCM(60,34,31) = ( 60 × 34 × 31 ) / 2
LCM(60,34,31) = 63240 / 2
LCM(60,34,31) = 31620
