Greatest Common Factor
We found the factors 278,419 . The biggest common factor number is the GCF number.
So the greatest common factor 278,419 is 1.
Lets's calculate LCM of 161,620
Given numbers has no common factors except 1. So, there LCM is their product i.e 99820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/99820
Therefore, the GCF of Fractions 278/161,419/620 is 1/99820
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 161,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(161,620) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(161,620) x common factors =1 x 1 = 1
LCM(161,620) = ( 161 × 620 ) / 1
LCM(161,620) = 99820 / 1
LCM(161,620) = 99820
