Given numbers are 396,162,834,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,162,834,680 is 84217320.
Find LCM of 396,162,834,680 with Prime Factorization
| 2 | 396, 162, 834, 680 |
| 2 | 198, 81, 417, 340 |
| 3 | 99, 81, 417, 170 |
| 3 | 33, 27, 139, 170 |
| 11, 9, 139, 170 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 9 x 139 x 170 = 84217320
Therefore, the lowest common multiple of 396,162,834,680 is 84217320.
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.
396 x 162 x 834 x 680 = 36381882240
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
834 : 1, 2, 3, 6, 139, 278, 417, 834
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,162,834,680, is 2.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
162:2x 3x 3x 3x 3
834:2x 3x 139
680:2x 2x 2x 5x 17
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 = 36381882240/(2x216)
LCM = 36381882240/432
LCM = 84217320
Thus, we can understand that the LCM of 396,162,834,680 is 84217320.
