Given numbers are 205,451,798,828,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 205,451,798,828,321 is 26571269340.
Find LCM of 205,451,798,828,321 with Prime Factorization
| 2 | 205, 451, 798, 828, 321 |
| 3 | 205, 451, 399, 414, 321 |
| 41 | 205, 451, 133, 138, 107 |
| 5, 11, 133, 138, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 5 x 11 x 133 x 138 x 107 = 26571269340
Therefore, the lowest common multiple of 205,451,798,828,321 is 26571269340.
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.
205 x 451 x 798 x 828 x 321 = 19609596772920
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.
205 : 1, 5, 41, 205
451 : 1, 11, 41, 451
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,451,798,828,321, is 1.
Now, the common factors can be found like this.
205:5x 41
451:11x 41
798:2x 3x 7x 19
828:2x 2x 3x 3x 23
321:3x 107
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 41 = 738
Therefore, the value for common factors is 738.
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 = 19609596772920/(1x738)
LCM = 19609596772920/738
LCM = 26571269340
Thus, we can understand that the LCM of 205,451,798,828,321 is 26571269340.
