1,2,4,8,11,22,44,88,89,178,356,712,979,1958,3916,7832
Greatest Common Factor
We found the factors 12,7832 . The biggest common factor number is the GCF number.
So the greatest common factor 12,7832 is 4.
Lets's calculate LCM of 505,2828
101 | 505, 2828 |
5, 28 |
∴ So the LCM of the given numbers is 101 x 5 x 28 = 14140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/14140
Therefore, the GCF of Fractions 12/505,7832/2828 is 4/14140
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 505,2828 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(505,2828) = 101
common factors(in case of two or more numbers have common factors) = 1
GCF(505,2828) x common factors =101 x 1 = 101
LCM(505,2828) = ( 505 × 2828 ) / 101
LCM(505,2828) = 1428140 / 101
LCM(505,2828) = 14140
