Given numbers are 561,423,216,687,333
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,423,216,687,333 is 16085346552.
Find LCM of 561,423,216,687,333 with Prime Factorization
| 3 | 561, 423, 216, 687, 333 |
| 3 | 187, 141, 72, 229, 111 |
| 187, 47, 24, 229, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 187 x 47 x 24 x 229 x 37 = 16085346552
Therefore, the lowest common multiple of 561,423,216,687,333 is 16085346552.
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.
561 x 423 x 216 x 687 x 333 = 11726217636408
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
423 : 1, 3, 9, 47, 141, 423
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
687 : 1, 3, 229, 687
333 : 1, 3, 9, 37, 111, 333
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,423,216,687,333, is 3.
Now, the common factors can be found like this.
561:3x 11x 17
423:3x 3x 47
216:2x 2x 2x 3x 3x 3
687:3x 229
333:3x 3x 37
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 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 11726217636408/(3x243)
LCM = 11726217636408/729
LCM = 16085346552
Thus, we can understand that the LCM of 561,423,216,687,333 is 16085346552.
