Greatest Common Factor
We found the factors 718,511 . The biggest common factor number is the GCF number.
So the greatest common factor 718,511 is 1.
Lets's calculate LCM of 219,817
Given numbers has no common factors except 1. So, there LCM is their product i.e 178923
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/178923
Therefore, the GCF of Fractions 718/219,511/817 is 1/178923
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 219,817 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(219,817) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(219,817) x common factors =1 x 1 = 1
LCM(219,817) = ( 219 × 817 ) / 1
LCM(219,817) = 178923 / 1
LCM(219,817) = 178923
