Given numbers are 403,156,923,432,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,156,923,432,686 is 4239759888.
Find LCM of 403,156,923,432,686 with Prime Factorization
| 2 | 403, 156, 923, 432, 686 |
| 2 | 403, 78, 923, 216, 343 |
| 3 | 403, 39, 923, 108, 343 |
| 13 | 403, 13, 923, 36, 343 |
| 31, 1, 71, 36, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 31 x 1 x 71 x 36 x 343 = 4239759888
Therefore, the lowest common multiple of 403,156,923,432,686 is 4239759888.
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.
403 x 156 x 923 x 432 x 686 = 17196466105728
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.
403 : 1, 13, 31, 403
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
923 : 1, 13, 71, 923
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,156,923,432,686, is 1.
Now, the common factors can be found like this.
403:13x 31
156:2x 2x 3x 13
923:13x 71
432:2x 2x 2x 2x 3x 3x 3
686:2x 7x 7x 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 3x 13x 13 = 4056
Therefore, the value for common factors is 4056.
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 = 17196466105728/(1x4056)
LCM = 17196466105728/4056
LCM = 4239759888
Thus, we can understand that the LCM of 403,156,923,432,686 is 4239759888.
