Given numbers are 289,555,849,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,555,849,407 is 499309635.
Find LCM of 289,555,849,407 with Prime Factorization
| 3 | 289, 555, 849, 407 |
| 37 | 289, 185, 283, 407 |
| 289, 5, 283, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 289 x 5 x 283 x 11 = 499309635
Therefore, the lowest common multiple of 289,555,849,407 is 499309635.
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.
289 x 555 x 849 x 407 = 55423369485
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.
289 : 1, 17, 289
555 : 1, 3, 5, 15, 37, 111, 185, 555
849 : 1, 3, 283, 849
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,555,849,407, is 1.
Now, the common factors can be found like this.
289:17x 17
555:3x 5x 37
849:3x 283
407:11x 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 = 55423369485/(1x111)
LCM = 55423369485/111
LCM = 499309635
Thus, we can understand that the LCM of 289,555,849,407 is 499309635.
