Given numbers are 249,286,664,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,286,664,856 is 30479592.
Find LCM of 249,286,664,856 with Prime Factorization
| 2 | 249, 286, 664, 856 |
| 2 | 249, 143, 332, 428 |
| 2 | 249, 143, 166, 214 |
| 83 | 249, 143, 83, 107 |
| 3, 143, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 83 x 3 x 143 x 1 x 107 = 30479592
Therefore, the lowest common multiple of 249,286,664,856 is 30479592.
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.
249 x 286 x 664 x 856 = 40476898176
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.
249 : 1, 3, 83, 249
286 : 1, 2, 11, 13, 22, 26, 143, 286
664 : 1, 2, 4, 8, 83, 166, 332, 664
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,286,664,856, is 1.
Now, the common factors can be found like this.
249:3x 83
286:2x 11x 13
664:2x 2x 2x 83
856:2x 2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 83 = 1328
Therefore, the value for common factors is 1328.
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 = 40476898176/(1x1328)
LCM = 40476898176/1328
LCM = 30479592
Thus, we can understand that the LCM of 249,286,664,856 is 30479592.
