Given numbers are 864,828,225,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,828,225,124 is 15400800.
Find LCM of 864,828,225,124 with Prime Factorization
| 2 | 864, 828, 225, 124 |
| 2 | 432, 414, 225, 62 |
| 3 | 216, 207, 225, 31 |
| 3 | 72, 69, 75, 31 |
| 24, 23, 25, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 24 x 23 x 25 x 31 = 15400800
Therefore, the lowest common multiple of 864,828,225,124 is 15400800.
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 828 x 225 x 124 = 19959436800
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
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,828,225,124, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
828:2x 2x 3x 3x 23
225:3x 3x 5x 5
124:2x 2x 31
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 3 = 1296
Therefore, the value for common factors is 1296.
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 = 19959436800/(1x1296)
LCM = 19959436800/1296
LCM = 15400800
Thus, we can understand that the LCM of 864,828,225,124 is 15400800.
