Given numbers are 801,855,675,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,855,675,474 is 180345150.
Find LCM of 801,855,675,474 with Prime Factorization
| 3 | 801, 855, 675, 474 |
| 3 | 267, 285, 225, 158 |
| 5 | 89, 95, 75, 158 |
| 89, 19, 15, 158 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 89 x 19 x 15 x 158 = 180345150
Therefore, the lowest common multiple of 801,855,675,474 is 180345150.
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.
801 x 855 x 675 x 474 = 219119357250
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.
801 : 1, 3, 9, 89, 267, 801
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
474 : 1, 2, 3, 6, 79, 158, 237, 474
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,855,675,474, is 3.
Now, the common factors can be found like this.
801:3x 3x 89
855:3x 3x 5x 19
675:3x 3x 3x 5x 5
474:2x 3x 79
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 = 219119357250/(3x405)
LCM = 219119357250/1215
LCM = 180345150
Thus, we can understand that the LCM of 801,855,675,474 is 180345150.
