Given numbers are 489,981,197,481,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,981,197,481,851 is 348494357133.
Find LCM of 489,981,197,481,851 with Prime Factorization
| 3 | 489, 981, 197, 481, 851 |
| 37 | 163, 327, 197, 481, 851 |
| 163, 327, 197, 13, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 163 x 327 x 197 x 13 x 23 = 348494357133
Therefore, the lowest common multiple of 489,981,197,481,851 is 348494357133.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
489 x 981 x 197 x 481 x 851 = 38682873641763
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
489 : 1, 3, 163, 489
981 : 1, 3, 9, 109, 327, 981
197 : 1, 197
481 : 1, 13, 37, 481
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,981,197,481,851, is 1.
Now, the common factors can be found like this.
489:3x 163
981:3x 3x 109
197:197
481:13x 37
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 37 = 111
Therefore, the value for common factors is 111.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 38682873641763/(1x111)
LCM = 38682873641763/111
LCM = 348494357133
Thus, we can understand that the LCM of 489,981,197,481,851 is 348494357133.
