Given numbers are 286,870,654,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,870,654,731 is 9912864390.
Find LCM of 286,870,654,731 with Prime Factorization
| 2 | 286, 870, 654, 731 |
| 3 | 143, 435, 327, 731 |
| 143, 145, 109, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 143 x 145 x 109 x 731 = 9912864390
Therefore, the lowest common multiple of 286,870,654,731 is 9912864390.
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 870 x 654 x 731 = 118954372680
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
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
654 : 1, 2, 3, 6, 109, 218, 327, 654
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,870,654,731, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
870:2x 3x 5x 29
654:2x 3x 109
731:17x 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 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 118954372680/(1x12)
LCM = 118954372680/12
LCM = 9912864390
Thus, we can understand that the LCM of 286,870,654,731 is 9912864390.
