Find LCM of 286,667,343,406,989 with Prime Factorization
| 2 | 286, 667, 343, 406, 989 |
| 7 | 143, 667, 343, 203, 989 |
| 23 | 143, 667, 49, 29, 989 |
| 29 | 143, 29, 49, 29, 43 |
| 143, 1, 49, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 29 x 143 x 1 x 49 x 1 x 43 = 2813548738
Therefore, the lowest common multiple of 286,667,343,406,989 is 2813548738.
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.
286 x 667 x 343 x 406 x 989 = 26272918115444
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
667 : 1, 23, 29, 667
343 : 1, 7, 49, 343
406 : 1, 2, 7, 14, 29, 58, 203, 406
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,667,343,406,989, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
667:23x 29
343:7x 7x 7
406:2x 7x 29
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 23x 29 = 9338
Therefore, the value for common factors is 9338.
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 = 26272918115444/(1x9338)
LCM = 26272918115444/9338
LCM = 2813548738
Thus, we can understand that the LCM of 286,667,343,406,989 is 2813548738.
