Given numbers are 515,455,663,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,455,663,481 is 88434255.
Find LCM of 515,455,663,481 with Prime Factorization
| 5 | 515, 455, 663, 481 |
| 13 | 103, 91, 663, 481 |
| 103, 7, 51, 37 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 103 x 7 x 51 x 37 = 88434255
Therefore, the lowest common multiple of 515,455,663,481 is 88434255.
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.
515 x 455 x 663 x 481 = 74726945475
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.
515 : 1, 5, 103, 515
455 : 1, 5, 7, 13, 35, 65, 91, 455
663 : 1, 3, 13, 17, 39, 51, 221, 663
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,455,663,481, is 1.
Now, the common factors can be found like this.
515:5x 103
455:5x 7x 13
663:3x 13x 17
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 13 = 845
Therefore, the value for common factors is 845.
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 = 74726945475/(1x845)
LCM = 74726945475/845
LCM = 88434255
Thus, we can understand that the LCM of 515,455,663,481 is 88434255.
