Find LCM of 864,438,808,299,657 with Prime Factorization
| 2 | 864, 438, 808, 299, 657 |
| 2 | 432, 219, 404, 299, 657 |
| 2 | 216, 219, 202, 299, 657 |
| 3 | 108, 219, 101, 299, 657 |
| 3 | 36, 73, 101, 299, 219 |
| 73 | 12, 73, 101, 299, 73 |
| 12, 1, 101, 299, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 73 x 12 x 1 x 101 x 299 x 1 = 1904711328
Therefore, the lowest common multiple of 864,438,808,299,657 is 1904711328.
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 438 x 808 x 299 x 657 = 60066976439808
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
438 : 1, 2, 3, 6, 73, 146, 219, 438
808 : 1, 2, 4, 8, 101, 202, 404, 808
299 : 1, 13, 23, 299
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,438,808,299,657, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
438:2x 3x 73
808:2x 2x 2x 101
299:13x 23
657:3x 3x 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 2x 2x 2x 3x 3x 3x 73 = 31536
Therefore, the value for common factors is 31536.
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 = 60066976439808/(1x31536)
LCM = 60066976439808/31536
LCM = 1904711328
Thus, we can understand that the LCM of 864,438,808,299,657 is 1904711328.
