List of positive integer factors of 2648 that divides 2648 without a remainder.
1,2,4,8,331,662,1324,2648
Greatest Common Factor
We found the factors 1686,2648 . The biggest common factor number is the GCF number.
So the greatest common factor 1686,2648 is 2.
Lets's calculate LCM of 64,179
Given numbers has no common factors except 1. So, there LCM is their product i.e 11456
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/11456
Therefore, the GCF of Fractions 1686/64,2648/179 is 2/11456
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 64,179 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,179) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(64,179) x common factors =1 x 1 = 1
LCM(64,179) = ( 64 × 179 ) / 1
LCM(64,179) = 11456 / 1
LCM(64,179) = 11456
