Lets's calculate GCF of 418,422
2 | 418, 422 |
209, 211 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 418
:1,2,11,19,22,38,209,418
Now, list down the factors of 422
:1,2,211,422
Greatest Common Factor
We found the factors 418,422 . The biggest common factor number is the GCF number.
So the greatest common factor 418,422 is 2.
Lets's calculate LCM of 123,479
Given numbers has no common factors except 1. So, there LCM is their product i.e 58917
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/58917
Therefore, the GCF of Fractions 418/123,422/479 is 2/58917
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 123,479 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(123,479) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(123,479) x common factors =1 x 1 = 1
LCM(123,479) = ( 123 × 479 ) / 1
LCM(123,479) = 58917 / 1
LCM(123,479) = 58917
