List of positive integer factors of 531 that divides 531 without a remainder.
1,3,9,59,177,531
Greatest Common Factor
We found the factors 2,690,531 . The biggest common factor number is the GCF number.
So the greatest common factor 2,690,531 is 1.
Lets's calculate LCM of 17,57,63
3 | 17, 57, 63 |
17, 19, 21 |
∴ So the LCM of the given numbers is 3 x 17 x 19 x 21 = 20349
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20349
Therefore, the GCF of Fractions 2/17,690/57,531/63 is 1/20349
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 17,57,63 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,57,63) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(17,57,63) x common factors =1 x 3 = 3
LCM(17,57,63) = ( 17 × 57 × 63 ) / 3
LCM(17,57,63) = 61047 / 3
LCM(17,57,63) = 20349
