So the greatest common factor 515,7220 is 5.
Lets's calculate LCM of 720,7804
2 | 720, 7804 |
2 | 360, 3902 |
180, 1951 |
∴ So the LCM of the given numbers is 2 x 2 x 180 x 1951 = 1404720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1404720
Therefore, the GCF of Fractions 515/720,7220/7804 is 5/1404720
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 720,7804 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(720,7804) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(720,7804) x common factors =4 x 1 = 4
LCM(720,7804) = ( 720 × 7804 ) / 4
LCM(720,7804) = 5618880 / 4
LCM(720,7804) = 1404720
