Find LCM of 864,736,458,216 with Prime Factorization
| 2 | 864, 736, 458, 216 |
| 2 | 432, 368, 229, 108 |
| 2 | 216, 184, 229, 54 |
| 2 | 108, 92, 229, 27 |
| 2 | 54, 46, 229, 27 |
| 3 | 27, 23, 229, 27 |
| 3 | 9, 23, 229, 9 |
| 3 | 3, 23, 229, 3 |
| 1, 23, 229, 1 |
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 3 x 1 x 23 x 229 x 1 = 4550688
Therefore, the lowest common multiple of 864,736,458,216 is 4550688.
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 736 x 458 x 216 = 62908710912
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
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
458 : 1, 2, 229, 458
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,736,458,216, is 2.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
736:2x 2x 2x 2x 2x 23
458:2x 229
216:2x 2x 2x 3x 3x 3
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 2x 2x 2x 3x 3x 3 = 6912
Therefore, the value for common factors is 6912.
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 = 62908710912/(2x6912)
LCM = 62908710912/13824
LCM = 4550688
Thus, we can understand that the LCM of 864,736,458,216 is 4550688.
