Factors of 215
List of positive integer factors of 215 that divides 215 without a remainder.
1,5,43,215
Greatest Common Factor
We found the factors 915,215 . The biggest common factor number is the GCF number.
So the greatest common factor 915,215 is 5.
Lets's calculate LCM of 1268,8569
Given numbers has no common factors except 1. So, there LCM is their product i.e 10865492
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/10865492
Therefore, the GCF of Fractions 915/1268,215/8569 is 5/10865492
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 1268,8569 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1268,8569) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(1268,8569) x common factors =1 x 1 = 1
LCM(1268,8569) = ( 1268 × 8569 ) / 1
LCM(1268,8569) = 10865492 / 1
LCM(1268,8569) = 10865492
