Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 1/35,124/60,452/42
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 1,124,452
Greatest Common Factor of Numerators i.e. GCF of 1,124,452 is 1 .
LCM of Denominators means LCM of 35,60,42 as per the given fractions.
LCM of 35,60,42 is 420 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 1,124,452
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,4,31,62,124
Factors of 452
List of positive integer factors of 452 that divides 452 without a remainder.
1,2,4,113,226,452
Greatest Common Factor
We found the factors 1,124,452 . The biggest common factor number is the GCF number.
So the greatest common factor 1,124,452 is 1.
Lets's calculate LCM of 35,60,42
2 | 35, 60, 42 |
3 | 35, 30, 21 |
5 | 35, 10, 7 |
7 | 7, 2, 7 |
1, 2, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 7 x 1 x 2 x 1 = 420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/420
Therefore, the GCF of Fractions 1/35,124/60,452/42 is 1/420
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 35,60,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,60,42) = 1
common factors(in case of two or more numbers have common factors) = 210
GCF(35,60,42) x common factors =1 x 210 = 210
LCM(35,60,42) = ( 35 × 60 × 42 ) / 210
LCM(35,60,42) = 88200 / 210
LCM(35,60,42) = 420
