Now, list down the factors of 684
:1,2,3,4,6,9,12,18,19,36,38,57,76,114,171,228,342,684
Greatest Common Factor
We found the factors 666,684 . The biggest common factor number is the GCF number.
So the greatest common factor 666,684 is 18.
Lets's calculate LCM of 13,253
Given numbers has no common factors except 1. So, there LCM is their product i.e 3289
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/3289
Therefore, the GCF of Fractions 666/13,684/253 is 18/3289
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 13,253 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,253) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(13,253) x common factors =1 x 1 = 1
LCM(13,253) = ( 13 × 253 ) / 1
LCM(13,253) = 3289 / 1
LCM(13,253) = 3289
