Given numbers are 286,169,405,860,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,169,405,860,803 is 9453349620.
Find LCM of 286,169,405,860,803 with Prime Factorization
| 2 | 286, 169, 405, 860, 803 |
| 5 | 143, 169, 405, 430, 803 |
| 11 | 143, 169, 81, 86, 803 |
| 13 | 13, 169, 81, 86, 73 |
| 1, 13, 81, 86, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 1 x 13 x 81 x 86 x 73 = 9453349620
Therefore, the lowest common multiple of 286,169,405,860,803 is 9453349620.
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 169 x 405 x 860 x 803 = 13518289956600
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
169 : 1, 13, 169
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,169,405,860,803, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
169:13x 13
405:3x 3x 3x 3x 5
860:2x 2x 5x 43
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 13 = 1430
Therefore, the value for common factors is 1430.
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 = 13518289956600/(1x1430)
LCM = 13518289956600/1430
LCM = 9453349620
Thus, we can understand that the LCM of 286,169,405,860,803 is 9453349620.
