Lets's calculate GCF of 556,5143
139 | 556, 5143 |
4, 37 |
∴ So the GCF of the given numbers is 139 = 139
Now, list down the factors of 556
:1,2,4,139,278,556
Now, list down the factors of 5143
:1,37,139,5143
Greatest Common Factor
We found the factors 556,5143 . The biggest common factor number is the GCF number.
So the greatest common factor 556,5143 is 139.
Lets's calculate LCM of 978,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 969198
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 139/969198
Therefore, the GCF of Fractions 556/978,5143/991 is 139/969198
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 978,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(978,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(978,991) x common factors =1 x 1 = 1
LCM(978,991) = ( 978 × 991 ) / 1
LCM(978,991) = 969198 / 1
LCM(978,991) = 969198
