List of positive integer factors of 142 that divides 142 without a remainder.
1,2,71,142
Greatest Common Factor
We found the factors 405,729,142 . The biggest common factor number is the GCF number.
So the greatest common factor 405,729,142 is 1.
Lets's calculate LCM of 52,13,17
13 | 52, 13, 17 |
4, 1, 17 |
∴ So the LCM of the given numbers is 13 x 4 x 1 x 17 = 884
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/884
Therefore, the GCF of Fractions 405/52,729/13,142/17 is 1/884
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 52,13,17 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(52,13,17) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(52,13,17) x common factors =1 x 13 = 13
LCM(52,13,17) = ( 52 × 13 × 17 ) / 13
LCM(52,13,17) = 11492 / 13
LCM(52,13,17) = 884
