Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Now, list down the factors of 211
:1,211
Greatest Common Factor
We found the factors 830,211 . The biggest common factor number is the GCF number.
So the greatest common factor 830,211 is 1.
Lets's calculate LCM of 289,885
Given numbers has no common factors except 1. So, there LCM is their product i.e 255765
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/255765
Therefore, the GCF of Fractions 830/289,211/885 is 1/255765
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 289,885 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(289,885) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(289,885) x common factors =1 x 1 = 1
LCM(289,885) = ( 289 × 885 ) / 1
LCM(289,885) = 255765 / 1
LCM(289,885) = 255765
