Lets's calculate GCF of 161,621
23 | 161, 621 |
7, 27 |
∴ So the GCF of the given numbers is 23 = 23
Now, list down the factors of 161
:1,7,23,161
Now, list down the factors of 621
:1,3,9,23,27,69,207,621
Greatest Common Factor
We found the factors 161,621 . The biggest common factor number is the GCF number.
So the greatest common factor 161,621 is 23.
Lets's calculate LCM of 55,4819
Given numbers has no common factors except 1. So, there LCM is their product i.e 265045
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/265045
Therefore, the GCF of Fractions 161/55,621/4819 is 23/265045
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 55,4819 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(55,4819) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(55,4819) x common factors =1 x 1 = 1
LCM(55,4819) = ( 55 × 4819 ) / 1
LCM(55,4819) = 265045 / 1
LCM(55,4819) = 265045
