Given numbers are 778,324,160,999
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,324,160,999 is 186533280.
Find LCM of 778,324,160,999 with Prime Factorization
| 2 | 778, 324, 160, 999 |
| 2 | 389, 162, 80, 999 |
| 3 | 389, 81, 40, 999 |
| 3 | 389, 27, 40, 333 |
| 3 | 389, 9, 40, 111 |
| 389, 3, 40, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 389 x 3 x 40 x 37 = 186533280
Therefore, the lowest common multiple of 778,324,160,999 is 186533280.
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.
778 x 324 x 160 x 999 = 40291188480
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.
778 : 1, 2, 389, 778
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,324,160,999, is 1.
Now, the common factors can be found like this.
778:2x 389
324:2x 2x 3x 3x 3x 3
160:2x 2x 2x 2x 2x 5
999:3x 3x 3x 37
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 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 40291188480/(1x216)
LCM = 40291188480/216
LCM = 186533280
Thus, we can understand that the LCM of 778,324,160,999 is 186533280.
