Given numbers are 406,417,805,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,417,805,851 is 720380010.
Find LCM of 406,417,805,851 with Prime Factorization
| 7 | 406, 417, 805, 851 |
| 23 | 58, 417, 115, 851 |
| 58, 417, 5, 37 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 58 x 417 x 5 x 37 = 720380010
Therefore, the lowest common multiple of 406,417,805,851 is 720380010.
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.
406 x 417 x 805 x 851 = 115981181610
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
417 : 1, 3, 139, 417
805 : 1, 5, 7, 23, 35, 115, 161, 805
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,417,805,851, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
417:3x 139
805:5x 7x 23
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 115981181610/(1x161)
LCM = 115981181610/161
LCM = 720380010
Thus, we can understand that the LCM of 406,417,805,851 is 720380010.
