The LCM of 465,286,783,289,561 is 10031302710.
Find LCM of 465,286,783,289,561 with Prime Factorization
| 3 | 465, 286, 783, 289, 561 |
| 11 | 155, 286, 261, 289, 187 |
| 17 | 155, 26, 261, 289, 17 |
| 155, 26, 261, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 17 x 155 x 26 x 261 x 1 x 17 = 10031302710
Therefore, the lowest common multiple of 465,286,783,289,561 is 10031302710.
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.
465 x 286 x 783 x 289 x 561 = 16882682460930
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.
465 : 1, 3, 5, 15, 31, 93, 155, 465
286 : 1, 2, 11, 13, 22, 26, 143, 286
783 : 1, 3, 9, 27, 29, 87, 261, 783
289 : 1, 17, 289
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 465,286,783,289,561, is 1.
Now, the common factors can be found like this.
465:3x 5x 31
286:2x 11x 13
783:3x 3x 3x 29
289:17x 17
561:3x 11x 17
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 11x 17 = 1683
Therefore, the value for common factors is 1683.
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 = 16882682460930/(1x1683)
LCM = 16882682460930/1683
LCM = 10031302710
Thus, we can understand that the LCM of 465,286,783,289,561 is 10031302710.
