Given numbers are 405,391,782,483
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,391,782,483 is 2216970.
Find LCM of 405,391,782,483 with Prime Factorization
| 3 | 405, 391, 782, 483 |
| 17 | 135, 391, 782, 161 |
| 23 | 135, 23, 46, 161 |
| 135, 1, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 23 x 135 x 1 x 2 x 7 = 2216970
Therefore, the lowest common multiple of 405,391,782,483 is 2216970.
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.
405 x 391 x 782 x 483 = 59811633630
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
391 : 1, 17, 23, 391
782 : 1, 2, 17, 23, 34, 46, 391, 782
483 : 1, 3, 7, 21, 23, 69, 161, 483
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,391,782,483, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
391:17x 23
782:2x 17x 23
483:3x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 23x 23 = 26979
Therefore, the value for common factors is 26979.
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 = 59811633630/(1x26979)
LCM = 59811633630/26979
LCM = 2216970
Thus, we can understand that the LCM of 405,391,782,483 is 2216970.
