Given numbers are 851,808,391,404
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,808,391,404 is 11689336.
Find LCM of 851,808,391,404 with Prime Factorization
| 2 | 851, 808, 391, 404 |
| 2 | 851, 404, 391, 202 |
| 23 | 851, 101, 391, 202 |
| 101 | 37, 101, 17, 202 |
| 37, 1, 17, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 101 x 37 x 1 x 17 x 2 = 11689336
Therefore, the lowest common multiple of 851,808,391,404 is 11689336.
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.
851 x 808 x 391 x 404 = 108617310112
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.
851 : 1, 23, 37, 851
808 : 1, 2, 4, 8, 101, 202, 404, 808
391 : 1, 17, 23, 391
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,808,391,404, is 1.
Now, the common factors can be found like this.
851:23x 37
808:2x 2x 2x 101
391:17x 23
404:2x 2x 101
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 23x 101 = 9292
Therefore, the value for common factors is 9292.
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 = 108617310112/(1x9292)
LCM = 108617310112/9292
LCM = 11689336
Thus, we can understand that the LCM of 851,808,391,404 is 11689336.
