Given numbers are 864,520,802,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,520,802,401 is 22520160.
Find LCM of 864,520,802,401 with Prime Factorization
| 2 | 864, 520, 802, 401 |
| 2 | 432, 260, 401, 401 |
| 2 | 216, 130, 401, 401 |
| 401 | 108, 65, 401, 401 |
| 108, 65, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 401 x 108 x 65 x 1 x 1 = 22520160
Therefore, the lowest common multiple of 864,520,802,401 is 22520160.
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 520 x 802 x 401 = 144489346560
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
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
802 : 1, 2, 401, 802
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,520,802,401, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
520:2x 2x 2x 5x 13
802:2x 401
401:401
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 401 = 6416
Therefore, the value for common factors is 6416.
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 = 144489346560/(1x6416)
LCM = 144489346560/6416
LCM = 22520160
Thus, we can understand that the LCM of 864,520,802,401 is 22520160.
