Given numbers are 249,687,754,585
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,687,754,585 is 644907510.
Find LCM of 249,687,754,585 with Prime Factorization
| 3 | 249, 687, 754, 585 |
| 13 | 83, 229, 754, 195 |
| 83, 229, 58, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 83 x 229 x 58 x 15 = 644907510
Therefore, the lowest common multiple of 249,687,754,585 is 644907510.
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 687 x 754 x 585 = 75454178670
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
687 : 1, 3, 229, 687
754 : 1, 2, 13, 26, 29, 58, 377, 754
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,687,754,585, is 1.
Now, the common factors can be found like this.
249:3x 83
687:3x 229
754:2x 13x 29
585:3x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 75454178670/(1x117)
LCM = 75454178670/117
LCM = 644907510
Thus, we can understand that the LCM of 249,687,754,585 is 644907510.
