Given numbers are 855,540,852,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,540,852,155 is 22582260.
Find LCM of 855,540,852,155 with Prime Factorization
| 2 | 855, 540, 852, 155 |
| 2 | 855, 270, 426, 155 |
| 3 | 855, 135, 213, 155 |
| 3 | 285, 45, 71, 155 |
| 5 | 95, 15, 71, 155 |
| 19, 3, 71, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 3 x 71 x 31 = 22582260
Therefore, the lowest common multiple of 855,540,852,155 is 22582260.
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 540 x 852 x 155 = 60972102000
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
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,540,852,155, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
540:2x 2x 3x 3x 3x 5
852:2x 2x 3x 71
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 5x 5 = 2700
Therefore, the value for common factors is 2700.
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 = 60972102000/(1x2700)
LCM = 60972102000/2700
LCM = 22582260
Thus, we can understand that the LCM of 855,540,852,155 is 22582260.
