Given numbers are 362,209,170,306,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 362,209,170,306,638 is 1678472730.
Find LCM of 362,209,170,306,638 with Prime Factorization
| 2 | 362, 209, 170, 306, 638 |
| 11 | 181, 209, 85, 153, 319 |
| 17 | 181, 19, 85, 153, 29 |
| 181, 19, 5, 9, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 181 x 19 x 5 x 9 x 29 = 1678472730
Therefore, the lowest common multiple of 362,209,170,306,638 is 1678472730.
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.
362 x 209 x 170 x 306 x 638 = 2510995204080
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.
362 : 1, 2, 181, 362
209 : 1, 11, 19, 209
170 : 1, 2, 5, 10, 17, 34, 85, 170
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 362,209,170,306,638, is 1.
Now, the common factors can be found like this.
362:2x 181
209:11x 19
170:2x 5x 17
306:2x 3x 3x 17
638:2x 11x 29
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 2x 11x 17 = 1496
Therefore, the value for common factors is 1496.
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 = 2510995204080/(1x1496)
LCM = 2510995204080/1496
LCM = 1678472730
Thus, we can understand that the LCM of 362,209,170,306,638 is 1678472730.
