:1,167
Greatest Common Factor
We found the factors 680,167 . The biggest common factor number is the GCF number.
So the greatest common factor 680,167 is 1.
Lets's calculate LCM of 821,494
Given numbers has no common factors except 1. So, there LCM is their product i.e 405574
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/405574
Therefore, the GCF of Fractions 680/821,167/494 is 1/405574
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 821,494 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(821,494) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(821,494) x common factors =1 x 1 = 1
LCM(821,494) = ( 821 × 494 ) / 1
LCM(821,494) = 405574 / 1
LCM(821,494) = 405574
