So the greatest common factor 415,2850 is 5.
Lets's calculate LCM of 825,420
3 | 825, 420 |
5 | 275, 140 |
55, 28 |
∴ So the LCM of the given numbers is 3 x 5 x 55 x 28 = 23100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/23100
Therefore, the GCF of Fractions 415/825,2850/420 is 5/23100
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 825,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(825,420) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(825,420) x common factors =15 x 1 = 15
LCM(825,420) = ( 825 × 420 ) / 15
LCM(825,420) = 346500 / 15
LCM(825,420) = 23100
