Find LCM of 231,621,288,896 with Prime Factorization
| 2 | 231, 621, 288, 896 |
| 2 | 231, 621, 144, 448 |
| 2 | 231, 621, 72, 224 |
| 2 | 231, 621, 36, 112 |
| 2 | 231, 621, 18, 56 |
| 3 | 231, 621, 9, 28 |
| 3 | 77, 207, 3, 28 |
| 7 | 77, 69, 1, 28 |
| 11, 69, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 7 x 11 x 69 x 1 x 4 = 6120576
Therefore, the lowest common multiple of 231,621,288,896 is 6120576.
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.
231 x 621 x 288 x 896 = 37017243648
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
621 : 1, 3, 9, 23, 27, 69, 207, 621
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,621,288,896, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
621:3x 3x 3x 23
288:2x 2x 2x 2x 2x 3x 3
896:2x 2x 2x 2x 2x 2x 2x 7
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 2x 3x 3x 3x 7 = 6048
Therefore, the value for common factors is 6048.
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 = 37017243648/(1x6048)
LCM = 37017243648/6048
LCM = 6120576
Thus, we can understand that the LCM of 231,621,288,896 is 6120576.
