1,3,5,15,647,1941,3235,9705
Greatest Common Factor
We found the factors 213,9705 . The biggest common factor number is the GCF number.
So the greatest common factor 213,9705 is 3.
Lets's calculate LCM of 485,620
5 | 485, 620 |
97, 124 |
∴ So the LCM of the given numbers is 5 x 97 x 124 = 60140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/60140
Therefore, the GCF of Fractions 213/485,9705/620 is 3/60140
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 485,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(485,620) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(485,620) x common factors =5 x 1 = 5
LCM(485,620) = ( 485 × 620 ) / 5
LCM(485,620) = 300700 / 5
LCM(485,620) = 60140
