Now, list down the factors of 331
:1,331
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 331,830 . The biggest common factor number is the GCF number.
So the greatest common factor 331,830 is 1.
Lets's calculate LCM of 201,638
Given numbers has no common factors except 1. So, there LCM is their product i.e 128238
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/128238
Therefore, the GCF of Fractions 331/201,830/638 is 1/128238
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 201,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(201,638) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(201,638) x common factors =1 x 1 = 1
LCM(201,638) = ( 201 × 638 ) / 1
LCM(201,638) = 128238 / 1
LCM(201,638) = 128238
