Now, list down the factors of 683
:1,683
Now, list down the factors of 690
:1,2,3,5,6,10,15,23,30,46,69,115,138,230,345,690
Greatest Common Factor
We found the factors 683,690 . The biggest common factor number is the GCF number.
So the greatest common factor 683,690 is 1.
Lets's calculate LCM of 61,217
Given numbers has no common factors except 1. So, there LCM is their product i.e 13237
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/13237
Therefore, the GCF of Fractions 683/61,690/217 is 1/13237
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 61,217 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,217) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,217) x common factors =1 x 1 = 1
LCM(61,217) = ( 61 × 217 ) / 1
LCM(61,217) = 13237 / 1
LCM(61,217) = 13237
