∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 27
:1,3,9,27
Now, list down the factors of 441
:1,3,7,9,21,49,63,147,441
Now, list down the factors of 645
:1,3,5,15,43,129,215,645
Greatest Common Factor
We found the factors 27,441,645 . The biggest common factor number is the GCF number.
So the greatest common factor 27,441,645 is 3.
Lets's calculate LCM of 44,40,170
2 | 44, 40, 170 |
2 | 22, 20, 85 |
5 | 11, 10, 85 |
11, 2, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 11 x 2 x 17 = 7480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/7480
Therefore, the GCF of Fractions 27/44,441/40,645/170 is 3/7480
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 44,40,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(44,40,170) = 2
common factors(in case of two or more numbers have common factors) = 20
GCF(44,40,170) x common factors =2 x 20 = 40
LCM(44,40,170) = ( 44 × 40 × 170 ) / 40
LCM(44,40,170) = 299200 / 40
LCM(44,40,170) = 7480
