Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 56/739,420/145
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 56,420
Greatest Common Factor of Numerators i.e. GCF of 56,420 is 28 .
LCM of Denominators means LCM of 739,145 as per the given fractions.
LCM of 739,145 is 107155 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 56,420
2 | 56, 420 |
2 | 28, 210 |
7 | 14, 105 |
2, 15 |
∴ So the GCF of the given numbers is 2 x 2 x 7 = 28

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 56,420 . The biggest common factor number is the GCF number.
So the greatest common factor 56,420 is 28.
Lets's calculate LCM of 739,145
Given numbers has no common factors except 1. So, there LCM is their product i.e 107155
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/107155
Therefore, the GCF of Fractions 56/739,420/145 is 28/107155
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 739,145 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(739,145) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(739,145) x common factors =1 x 1 = 1
LCM(739,145) = ( 739 × 145 ) / 1
LCM(739,145) = 107155 / 1
LCM(739,145) = 107155
