Given numbers are 531,993,645,270,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,993,645,270,811 is 183879400590.
Find LCM of 531,993,645,270,811 with Prime Factorization
| 3 | 531, 993, 645, 270, 811 |
| 3 | 177, 331, 215, 90, 811 |
| 5 | 59, 331, 215, 30, 811 |
| 59, 331, 43, 6, 811 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 59 x 331 x 43 x 6 x 811 = 183879400590
Therefore, the lowest common multiple of 531,993,645,270,811 is 183879400590.
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.
531 x 993 x 645 x 270 x 811 = 74471157238950
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.
531 : 1, 3, 9, 59, 177, 531
993 : 1, 3, 331, 993
645 : 1, 3, 5, 15, 43, 129, 215, 645
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,993,645,270,811, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
993:3x 331
645:3x 5x 43
270:2x 3x 3x 3x 5
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 74471157238950/(1x405)
LCM = 74471157238950/405
LCM = 183879400590
Thus, we can understand that the LCM of 531,993,645,270,811 is 183879400590.
