Given numbers are 499,840,243,639,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 499,840,243,639,819 is 31337659080.
Find LCM of 499,840,243,639,819 with Prime Factorization
| 3 | 499, 840, 243, 639, 819 |
| 3 | 499, 280, 81, 213, 273 |
| 7 | 499, 280, 27, 71, 91 |
| 499, 40, 27, 71, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 499 x 40 x 27 x 71 x 13 = 31337659080
Therefore, the lowest common multiple of 499,840,243,639,819 is 31337659080.
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.
499 x 840 x 243 x 639 x 819 = 53305358095080
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.
499 : 1, 499
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
243 : 1, 3, 9, 27, 81, 243
639 : 1, 3, 9, 71, 213, 639
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 499,840,243,639,819, is 1.
Now, the common factors can be found like this.
499:499
840:2x 2x 2x 3x 5x 7
243:3x 3x 3x 3x 3
639:3x 3x 71
819:3x 3x 7x 13
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 3x 7 = 1701
Therefore, the value for common factors is 1701.
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 = 53305358095080/(1x1701)
LCM = 53305358095080/1701
LCM = 31337659080
Thus, we can understand that the LCM of 499,840,243,639,819 is 31337659080.
