Now, list down the factors of 151
:1,151
Now, list down the factors of 838
:1,2,419,838
Greatest Common Factor
We found the factors 151,838 . The biggest common factor number is the GCF number.
So the greatest common factor 151,838 is 1.
Lets's calculate LCM of 643,258
Given numbers has no common factors except 1. So, there LCM is their product i.e 165894
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/165894
Therefore, the GCF of Fractions 151/643,838/258 is 1/165894
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 643,258 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,258) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,258) x common factors =1 x 1 = 1
LCM(643,258) = ( 643 × 258 ) / 1
LCM(643,258) = 165894 / 1
LCM(643,258) = 165894
