Given numbers are 399,463,646,469
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,463,646,469 is 420830886.
Find LCM of 399,463,646,469 with Prime Factorization
| 7 | 399, 463, 646, 469 |
| 19 | 57, 463, 646, 67 |
| 3, 463, 34, 67 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 3 x 463 x 34 x 67 = 420830886
Therefore, the lowest common multiple of 399,463,646,469 is 420830886.
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.
399 x 463 x 646 x 469 = 55970507838
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
463 : 1, 463
646 : 1, 2, 17, 19, 34, 38, 323, 646
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,463,646,469, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
463:463
646:2x 17x 19
469:7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 55970507838/(1x133)
LCM = 55970507838/133
LCM = 420830886
Thus, we can understand that the LCM of 399,463,646,469 is 420830886.
