Greatest Common Factor
We found the factors 413,939 . The biggest common factor number is the GCF number.
So the greatest common factor 413,939 is 1.
Lets's calculate LCM of 619,840
Given numbers has no common factors except 1. So, there LCM is their product i.e 519960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/519960
Therefore, the GCF of Fractions 413/619,939/840 is 1/519960
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 619,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(619,840) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(619,840) x common factors =1 x 1 = 1
LCM(619,840) = ( 619 × 840 ) / 1
LCM(619,840) = 519960 / 1
LCM(619,840) = 519960
