Greatest Common Factor
We found the factors 623,698 . The biggest common factor number is the GCF number.
So the greatest common factor 623,698 is 1.
Lets's calculate LCM of 18,821
Given numbers has no common factors except 1. So, there LCM is their product i.e 14778
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14778
Therefore, the GCF of Fractions 623/18,698/821 is 1/14778
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 18,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,821) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(18,821) x common factors =1 x 1 = 1
LCM(18,821) = ( 18 × 821 ) / 1
LCM(18,821) = 14778 / 1
LCM(18,821) = 14778
