Given numbers are 864,238,337,411,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,238,337,411,747 is 393993688032.
Find LCM of 864,238,337,411,747 with Prime Factorization
| 2 | 864, 238, 337, 411, 747 |
| 3 | 432, 119, 337, 411, 747 |
| 3 | 144, 119, 337, 137, 249 |
| 48, 119, 337, 137, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 48 x 119 x 337 x 137 x 83 = 393993688032
Therefore, the lowest common multiple of 864,238,337,411,747 is 393993688032.
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.
864 x 238 x 337 x 411 x 747 = 21275659153728
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
238 : 1, 2, 7, 14, 17, 34, 119, 238
337 : 1, 337
411 : 1, 3, 137, 411
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,238,337,411,747, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
238:2x 7x 17
337:337
411:3x 137
747:3x 3x 83
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 3 = 54
Therefore, the value for common factors is 54.
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 = 21275659153728/(1x54)
LCM = 21275659153728/54
LCM = 393993688032
Thus, we can understand that the LCM of 864,238,337,411,747 is 393993688032.
