So the greatest common factor 279,521 is 1.
Lets's calculate LCM of 480,159
3 | 480, 159 |
160, 53 |
∴ So the LCM of the given numbers is 3 x 160 x 53 = 25440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25440
Therefore, the GCF of Fractions 279/480,521/159 is 1/25440
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 480,159 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(480,159) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(480,159) x common factors =3 x 1 = 3
LCM(480,159) = ( 480 × 159 ) / 3
LCM(480,159) = 76320 / 3
LCM(480,159) = 25440
