Given numbers are 286,742,398,583
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,742,398,583 is 21115094.
Find LCM of 286,742,398,583 with Prime Factorization
| 2 | 286, 742, 398, 583 |
| 11 | 143, 371, 199, 583 |
| 53 | 13, 371, 199, 53 |
| 13, 7, 199, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 53 x 13 x 7 x 199 x 1 = 21115094
Therefore, the lowest common multiple of 286,742,398,583 is 21115094.
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 742 x 398 x 583 = 49240399208
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
742 : 1, 2, 7, 14, 53, 106, 371, 742
398 : 1, 2, 199, 398
583 : 1, 11, 53, 583
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,742,398,583, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
742:2x 7x 53
398:2x 199
583:11x 53
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 11x 53 = 2332
Therefore, the value for common factors is 2332.
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 = 49240399208/(1x2332)
LCM = 49240399208/2332
LCM = 21115094
Thus, we can understand that the LCM of 286,742,398,583 is 21115094.
