Greatest Common Factor
We found the factors 207,985 . The biggest common factor number is the GCF number.
So the greatest common factor 207,985 is 1.
Lets's calculate LCM of 288,145
Given numbers has no common factors except 1. So, there LCM is their product i.e 41760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/41760
Therefore, the GCF of Fractions 207/288,985/145 is 1/41760
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 288,145 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(288,145) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(288,145) x common factors =1 x 1 = 1
LCM(288,145) = ( 288 × 145 ) / 1
LCM(288,145) = 41760 / 1
LCM(288,145) = 41760
