Given numbers are 60,540,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 60,540,855 is 10260.
Find LCM of 60,540,855 with Prime Factorization
| 2 | 60, 540, 855 |
| 2 | 30, 270, 855 |
| 3 | 15, 135, 855 |
| 3 | 5, 45, 285 |
| 5 | 5, 15, 95 |
| 1, 3, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 1 x 3 x 19 = 10260
Therefore, the lowest common multiple of 60,540,855 is 10260.
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.
60 x 540 x 855 = 27702000
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.
60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
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
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
15 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 60,540,855, is 15.
Now, the common factors can be found like this.
60:2x 2x 3x 5
540:2x 2x 3x 3x 3x 5
855:3x 3x 5x 19
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 5 = 180
Therefore, the value for common factors is 180.
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 = 27702000/(15x180)
LCM = 27702000/2700
LCM = 10260
Thus, we can understand that the LCM of 60,540,855 is 10260.
