Lets's calculate GCF of 618,622
2 | 618, 622 |
309, 311 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 618
:1,2,3,6,103,206,309,618
Now, list down the factors of 622
:1,2,311,622
Greatest Common Factor
We found the factors 618,622 . The biggest common factor number is the GCF number.
So the greatest common factor 618,622 is 2.
Lets's calculate LCM of 302,457
Given numbers has no common factors except 1. So, there LCM is their product i.e 138014
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/138014
Therefore, the GCF of Fractions 618/302,622/457 is 2/138014
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 302,457 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(302,457) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(302,457) x common factors =1 x 1 = 1
LCM(302,457) = ( 302 × 457 ) / 1
LCM(302,457) = 138014 / 1
LCM(302,457) = 138014
