Lets's calculate GCF of 308,605
11 | 308, 605 |
28, 55 |
∴ So the GCF of the given numbers is 11 = 11
Now, list down the factors of 308
:1,2,4,7,11,14,22,28,44,77,154,308
Now, list down the factors of 605
:1,5,11,55,121,605
Greatest Common Factor
We found the factors 308,605 . The biggest common factor number is the GCF number.
So the greatest common factor 308,605 is 11.
Lets's calculate LCM of 109,402
Given numbers has no common factors except 1. So, there LCM is their product i.e 43818
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/43818
Therefore, the GCF of Fractions 308/109,605/402 is 11/43818
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 109,402 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(109,402) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(109,402) x common factors =1 x 1 = 1
LCM(109,402) = ( 109 × 402 ) / 1
LCM(109,402) = 43818 / 1
LCM(109,402) = 43818
