So the greatest common factor 248,992 is 248.
Lets's calculate LCM of 621,810
3 | 621, 810 |
3 | 207, 270 |
3 | 69, 90 |
23, 30 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 23 x 30 = 18630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 248/18630
Therefore, the GCF of Fractions 248/621,992/810 is 248/18630
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 621,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(621,810) = 27
common factors(in case of two or more numbers have common factors) = 1
GCF(621,810) x common factors =27 x 1 = 27
LCM(621,810) = ( 621 × 810 ) / 27
LCM(621,810) = 503010 / 27
LCM(621,810) = 18630
