Greatest Common Factor
We found the factors 225,2280 . The biggest common factor number is the GCF number.
So the greatest common factor 225,2280 is 15.
Lets's calculate LCM of 535,388
Given numbers has no common factors except 1. So, there LCM is their product i.e 207580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/207580
Therefore, the GCF of Fractions 225/535,2280/388 is 15/207580
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 535,388 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(535,388) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(535,388) x common factors =1 x 1 = 1
LCM(535,388) = ( 535 × 388 ) / 1
LCM(535,388) = 207580 / 1
LCM(535,388) = 207580
Here are some samples of GCF of Fractions calculations.
