Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 93/385,420/640
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 93,420
Greatest Common Factor of Numerators i.e. GCF of 93,420 is 3 .
LCM of Denominators means LCM of 385,640 as per the given fractions.
LCM of 385,640 is 49280 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 93,420
3 | 93, 420 |
31, 140 |
∴ So the GCF of the given numbers is 3 = 3

1,3,31,93
Factors of 420
List of positive integer factors of 420 that divides 420 without a remainder.
1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Greatest Common Factor
We found the factors 93,420 . The biggest common factor number is the GCF number.
So the greatest common factor 93,420 is 3.
Lets's calculate LCM of 385,640
5 | 385, 640 |
77, 128 |
∴ So the LCM of the given numbers is 5 x 77 x 128 = 49280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/49280
Therefore, the GCF of Fractions 93/385,420/640 is 3/49280
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 385,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(385,640) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(385,640) x common factors =5 x 1 = 5
LCM(385,640) = ( 385 × 640 ) / 5
LCM(385,640) = 246400 / 5
LCM(385,640) = 49280
