Given numbers are 855,435,909,156,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,435,909,156,813 is 35290525140.
Find LCM of 855,435,909,156,813 with Prime Factorization
| 3 | 855, 435, 909, 156, 813 |
| 3 | 285, 145, 303, 52, 271 |
| 5 | 95, 145, 101, 52, 271 |
| 19, 29, 101, 52, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 29 x 101 x 52 x 271 = 35290525140
Therefore, the lowest common multiple of 855,435,909,156,813 is 35290525140.
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.
855 x 435 x 909 x 156 x 813 = 42877988045100
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
435 : 1, 3, 5, 15, 29, 87, 145, 435
909 : 1, 3, 9, 101, 303, 909
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
813 : 1, 3, 271, 813
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,435,909,156,813, is 3.
Now, the common factors can be found like this.
855:3x 3x 5x 19
435:3x 5x 29
909:3x 3x 101
156:2x 2x 3x 13
813:3x 271
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 = 42877988045100/(3x405)
LCM = 42877988045100/1215
LCM = 35290525140
Thus, we can understand that the LCM of 855,435,909,156,813 is 35290525140.
