Given numbers are 286,689,507,898
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,689,507,898 is 265431738.
Find LCM of 286,689,507,898 with Prime Factorization
| 2 | 286, 689, 507, 898 |
| 13 | 143, 689, 507, 449 |
| 11, 53, 39, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 11 x 53 x 39 x 449 = 265431738
Therefore, the lowest common multiple of 286,689,507,898 is 265431738.
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 689 x 507 x 898 = 89715927444
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
689 : 1, 13, 53, 689
507 : 1, 3, 13, 39, 169, 507
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,689,507,898, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
689:13x 53
507:3x 13x 13
898:2x 449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 89715927444/(1x338)
LCM = 89715927444/338
LCM = 265431738
Thus, we can understand that the LCM of 286,689,507,898 is 265431738.
