The HCF of 321,141 is 3.
Lets's calculate GCF of 321,141
3 | 321, 141 |
107, 47 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 321
:1,3,107,321
Now, list down the factors of 141
:1,3,47,141
Greatest Common Factor
We found the factors 321,141 . The biggest common factor number is the GCF number.
So the greatest common factor 321,141 is 3.
Lets's calculate LCM of 268,638
2 | 268, 638 |
134, 319 |
∴ So the LCM of the given numbers is 2 x 134 x 319 = 85492
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/85492
Therefore, the GCF of Fractions 321/268,141/638 is 3/85492
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 268,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(268,638) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(268,638) x common factors =2 x 1 = 2
LCM(268,638) = ( 268 × 638 ) / 2
LCM(268,638) = 170984 / 2
LCM(268,638) = 85492
