Given numbers are 286,340,489,645,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,340,489,645,849 is 289320165420.
Find LCM of 286,340,489,645,849 with Prime Factorization
| 2 | 286, 340, 489, 645, 849 |
| 3 | 143, 170, 489, 645, 849 |
| 5 | 143, 170, 163, 215, 283 |
| 143, 34, 163, 43, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 143 x 34 x 163 x 43 x 283 = 289320165420
Therefore, the lowest common multiple of 286,340,489,645,849 is 289320165420.
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 340 x 489 x 645 x 849 = 26038814887800
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
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
489 : 1, 3, 163, 489
645 : 1, 3, 5, 15, 43, 129, 215, 645
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,340,489,645,849, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
340:2x 2x 5x 17
489:3x 163
645:3x 5x 43
849:3x 283
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 26038814887800/(1x90)
LCM = 26038814887800/90
LCM = 289320165420
Thus, we can understand that the LCM of 286,340,489,645,849 is 289320165420.
