Now, list down the factors of 258
:1,2,3,6,43,86,129,258
Now, list down the factors of 457
:1,457
Greatest Common Factor
We found the factors 258,457 . The biggest common factor number is the GCF number.
So the greatest common factor 258,457 is 1.
Lets's calculate LCM of 83,818
Given numbers has no common factors except 1. So, there LCM is their product i.e 67894
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/67894
Therefore, the GCF of Fractions 258/83,457/818 is 1/67894
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 83,818 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,818) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,818) x common factors =1 x 1 = 1
LCM(83,818) = ( 83 × 818 ) / 1
LCM(83,818) = 67894 / 1
LCM(83,818) = 67894
