Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 70/49,421/19,982/690
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 70,421,982
Greatest Common Factor of Numerators i.e. GCF of 70,421,982 is 1 .
LCM of Denominators means LCM of 49,19,690 as per the given fractions.
LCM of 49,19,690 is 642390 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 70,421,982
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 70
List of positive integer factors of 70 that divides 70 without a remainder.
1,2,5,7,10,14,35,70
Factors of 421

1,421
Factors of 982
List of positive integer factors of 982 that divides 982 without a remainder.
1,2,491,982
Greatest Common Factor
We found the factors 70,421,982 . The biggest common factor number is the GCF number.
So the greatest common factor 70,421,982 is 1.
Lets's calculate LCM of 49,19,690
Given numbers has no common factors except 1. So, there LCM is their product i.e 642390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/642390
Therefore, the GCF of Fractions 70/49,421/19,982/690 is 1/642390
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 49,19,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,19,690) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,19,690) x common factors =1 x 1 = 1
LCM(49,19,690) = ( 49 × 19 × 690 ) / 1
LCM(49,19,690) = 642390 / 1
LCM(49,19,690) = 642390
