So the greatest common factor 546,930 is 6.
Lets's calculate LCM of 630,255
3 | 630, 255 |
5 | 210, 85 |
42, 17 |
∴ So the LCM of the given numbers is 3 x 5 x 42 x 17 = 10710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/10710
Therefore, the GCF of Fractions 546/630,930/255 is 6/10710
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 630,255 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(630,255) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(630,255) x common factors =15 x 1 = 15
LCM(630,255) = ( 630 × 255 ) / 15
LCM(630,255) = 160650 / 15
LCM(630,255) = 10710
