Lets's calculate GCF of 574,656
2 | 574, 656 |
41 | 287, 328 |
7, 8 |
∴ So the GCF of the given numbers is 2 x 41 = 82
Now, list down the factors of 574
:1,2,7,14,41,82,287,574
Now, list down the factors of 656
:1,2,4,8,16,41,82,164,328,656
Greatest Common Factor
We found the factors 574,656 . The biggest common factor number is the GCF number.
So the greatest common factor 574,656 is 82.
Lets's calculate LCM of 84,170
2 | 84, 170 |
42, 85 |
∴ So the LCM of the given numbers is 2 x 42 x 85 = 7140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 82/7140
Therefore, the GCF of Fractions 574/84,656/170 is 82/7140
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 84,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,170) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(84,170) x common factors =2 x 1 = 2
LCM(84,170) = ( 84 × 170 ) / 2
LCM(84,170) = 14280 / 2
LCM(84,170) = 7140
