Given numbers are 177,423,138,855,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 177,423,138,855,255 is 1854055530.
Find LCM of 177,423,138,855,255 with Prime Factorization
| 3 | 177, 423, 138, 855, 255 |
| 3 | 59, 141, 46, 285, 85 |
| 5 | 59, 47, 46, 95, 85 |
| 59, 47, 46, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 59 x 47 x 46 x 19 x 17 = 1854055530
Therefore, the lowest common multiple of 177,423,138,855,255 is 1854055530.
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.
177 x 423 x 138 x 855 x 255 = 2252677468950
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.
177 : 1, 3, 59, 177
423 : 1, 3, 9, 47, 141, 423
138 : 1, 2, 3, 6, 23, 46, 69, 138
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
255 : 1, 3, 5, 15, 17, 51, 85, 255
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,423,138,855,255, is 3.
Now, the common factors can be found like this.
177:3x 59
423:3x 3x 47
138:2x 3x 23
855:3x 3x 5x 19
255:3x 5x 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 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 2252677468950/(3x405)
LCM = 2252677468950/1215
LCM = 1854055530
Thus, we can understand that the LCM of 177,423,138,855,255 is 1854055530.
