The LCM of 824,864,138,699 is 476908128.
Find LCM of 824,864,138,699 with Prime Factorization
| 2 | 824, 864, 138, 699 |
| 2 | 412, 432, 69, 699 |
| 2 | 206, 216, 69, 699 |
| 3 | 103, 108, 69, 699 |
| 103, 36, 23, 233 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 103 x 36 x 23 x 233 = 476908128
Therefore, the lowest common multiple of 824,864,138,699 is 476908128.
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.
824 x 864 x 138 x 699 = 68674770432
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
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
138 : 1, 2, 3, 6, 23, 46, 69, 138
699 : 1, 3, 233, 699
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,864,138,699, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
864:2x 2x 2x 2x 2x 3x 3x 3
138:2x 3x 23
699:3x 233
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 3 = 144
Therefore, the value for common factors is 144.
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 = 68674770432/(1x144)
LCM = 68674770432/144
LCM = 476908128
Thus, we can understand that the LCM of 824,864,138,699 is 476908128.
