:1,2,3,4,6,9,12,18,27,36,54,108
Greatest Common Factor
We found the factors 648,108 . The biggest common factor number is the GCF number.
So the greatest common factor 648,108 is 108.
Lets's calculate LCM of 662,281
Given numbers has no common factors except 1. So, there LCM is their product i.e 186022
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 108/186022
Therefore, the GCF of Fractions 648/662,108/281 is 108/186022
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 662,281 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(662,281) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(662,281) x common factors =1 x 1 = 1
LCM(662,281) = ( 662 × 281 ) / 1
LCM(662,281) = 186022 / 1
LCM(662,281) = 186022
