The factors of 111 are 1, 3, 37, 111
The factors of 321 are 1, 3, 107, 321
The HCF of 111,321 is 3.
Lets's calculate GCF of 111,321
3 | 111, 321 |
37, 107 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 111
:1,3,37,111
Now, list down the factors of 321
:1,3,107,321
Greatest Common Factor
We found the factors 111,321 . The biggest common factor number is the GCF number.
So the greatest common factor 111,321 is 3.
Lets's calculate LCM of 415,785
5 | 415, 785 |
83, 157 |
∴ So the LCM of the given numbers is 5 x 83 x 157 = 65155
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/65155
Therefore, the GCF of Fractions 111/415,321/785 is 3/65155
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 415,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(415,785) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(415,785) x common factors =5 x 1 = 5
LCM(415,785) = ( 415 × 785 ) / 5
LCM(415,785) = 325775 / 5
LCM(415,785) = 65155
