Given numbers are 455,396,617,465,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,396,617,465,915 is 210224474460.
Find LCM of 455,396,617,465,915 with Prime Factorization
| 3 | 455, 396, 617, 465, 915 |
| 5 | 455, 132, 617, 155, 305 |
| 91, 132, 617, 31, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 91 x 132 x 617 x 31 x 61 = 210224474460
Therefore, the lowest common multiple of 455,396,617,465,915 is 210224474460.
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.
455 x 396 x 617 x 465 x 915 = 47300506753500
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
617 : 1, 617
465 : 1, 3, 5, 15, 31, 93, 155, 465
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,396,617,465,915, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
396:2x 2x 3x 3x 11
617:617
465:3x 5x 31
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 47300506753500/(1x225)
LCM = 47300506753500/225
LCM = 210224474460
Thus, we can understand that the LCM of 455,396,617,465,915 is 210224474460.
