Given numbers are 396,802,768,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,802,768,162 is 91466496.
Find LCM of 396,802,768,162 with Prime Factorization
| 2 | 396, 802, 768, 162 |
| 2 | 198, 401, 384, 81 |
| 3 | 99, 401, 192, 81 |
| 3 | 33, 401, 64, 27 |
| 11, 401, 64, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 401 x 64 x 9 = 91466496
Therefore, the lowest common multiple of 396,802,768,162 is 91466496.
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 802 x 768 x 162 = 39513526272
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
802 : 1, 2, 401, 802
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,802,768,162, is 2.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
802:2x 401
768:2x 2x 2x 2x 2x 2x 2x 2x 3
162:2x 3x 3x 3x 3
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 = 39513526272/(2x216)
LCM = 39513526272/432
LCM = 91466496
Thus, we can understand that the LCM of 396,802,768,162 is 91466496.
