:1,7,59,413
Now, list down the factors of 761
:1,761
Greatest Common Factor
We found the factors 413,761 . The biggest common factor number is the GCF number.
So the greatest common factor 413,761 is 1.
Lets's calculate LCM of 402,985
Given numbers has no common factors except 1. So, there LCM is their product i.e 395970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/395970
Therefore, the GCF of Fractions 413/402,761/985 is 1/395970
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 402,985 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(402,985) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(402,985) x common factors =1 x 1 = 1
LCM(402,985) = ( 402 × 985 ) / 1
LCM(402,985) = 395970 / 1
LCM(402,985) = 395970
