:1,3,13,39,169,507
Greatest Common Factor
We found the factors 780,507 . The biggest common factor number is the GCF number.
So the greatest common factor 780,507 is 39.
Lets's calculate LCM of 33,8169
3 | 33, 8169 |
11, 2723 |
∴ So the LCM of the given numbers is 3 x 11 x 2723 = 89859
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 39/89859
Therefore, the GCF of Fractions 780/33,507/8169 is 39/89859
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 33,8169 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(33,8169) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(33,8169) x common factors =3 x 1 = 3
LCM(33,8169) = ( 33 × 8169 ) / 3
LCM(33,8169) = 269577 / 3
LCM(33,8169) = 89859
