Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 503/17,500/68,501/21
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 503,500,501
Greatest Common Factor of Numerators i.e. GCF of 503,500,501 is 1 .
LCM of Denominators means LCM of 17,68,21 as per the given fractions.
LCM of 17,68,21 is 1428 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 503,500,501
∴ So GCF of numbers is 1 because of no common factors present between them.

List of positive integer factors of 501 that divides 501 without a remainder.
1,3,167,501
Greatest Common Factor
We found the factors 503,500,501 . The biggest common factor number is the GCF number.
So the greatest common factor 503,500,501 is 1.
Lets's calculate LCM of 17,68,21
17 | 17, 68, 21 |
1, 4, 21 |
∴ So the LCM of the given numbers is 17 x 1 x 4 x 21 = 1428
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1428
Therefore, the GCF of Fractions 503/17,500/68,501/21 is 1/1428
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 17,68,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,68,21) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(17,68,21) x common factors =1 x 17 = 17
LCM(17,68,21) = ( 17 × 68 × 21 ) / 17
LCM(17,68,21) = 24276 / 17
LCM(17,68,21) = 1428
