So the greatest common factor 29,42,213 is 1.
Lets's calculate LCM of 945,679,485
5 | 945, 679, 485 |
7 | 189, 679, 97 |
97 | 27, 97, 97 |
27, 1, 1 |
∴ So the LCM of the given numbers is 5 x 7 x 97 x 27 x 1 x 1 = 91665
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/91665
Therefore, the GCF of Fractions 29/945,42/679,213/485 is 1/91665
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 945,679,485 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(945,679,485) = 1
common factors(in case of two or more numbers have common factors) = 3395
GCF(945,679,485) x common factors =1 x 3395 = 3395
LCM(945,679,485) = ( 945 × 679 × 485 ) / 3395
LCM(945,679,485) = 311202675 / 3395
LCM(945,679,485) = 91665
