Now, list down the factors of 203
:1,7,29,203
Now, list down the factors of 645
:1,3,5,15,43,129,215,645
Greatest Common Factor
We found the factors 203,645 . The biggest common factor number is the GCF number.
So the greatest common factor 203,645 is 1.
Lets's calculate LCM of 413,187
Given numbers has no common factors except 1. So, there LCM is their product i.e 77231
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/77231
Therefore, the GCF of Fractions 203/413,645/187 is 1/77231
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 413,187 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(413,187) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(413,187) x common factors =1 x 1 = 1
LCM(413,187) = ( 413 × 187 ) / 1
LCM(413,187) = 77231 / 1
LCM(413,187) = 77231
