Factors of 204
List of positive integer factors of 204 that divides 204 without a remainder.
1,2,3,4,6,12,17,34,51,68,102,204
Greatest Common Factor
We found the factors 680,204 . The biggest common factor number is the GCF number.
So the greatest common factor 680,204 is 68.
Lets's calculate LCM of 542,170
2 | 542, 170 |
271, 85 |
∴ So the LCM of the given numbers is 2 x 271 x 85 = 46070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 68/46070
Therefore, the GCF of Fractions 680/542,204/170 is 68/46070
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 542,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(542,170) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(542,170) x common factors =2 x 1 = 2
LCM(542,170) = ( 542 × 170 ) / 2
LCM(542,170) = 92140 / 2
LCM(542,170) = 46070
