Given numbers are 835,280,290,230,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 835,280,290,230,155 is 966856520.
Find LCM of 835,280,290,230,155 with Prime Factorization
| 2 | 835, 280, 290, 230, 155 |
| 5 | 835, 140, 145, 115, 155 |
| 167, 28, 29, 23, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 167 x 28 x 29 x 23 x 31 = 966856520
Therefore, the lowest common multiple of 835,280,290,230,155 is 966856520.
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.
835 x 280 x 290 x 230 x 155 = 2417141300000
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.
835 : 1, 5, 167, 835
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
290 : 1, 2, 5, 10, 29, 58, 145, 290
230 : 1, 2, 5, 10, 23, 46, 115, 230
155 : 1, 5, 31, 155
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 835,280,290,230,155, is 5.
Now, the common factors can be found like this.
835:5x 167
280:2x 2x 2x 5x 7
290:2x 5x 29
230:2x 5x 23
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 5x 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 2417141300000/(5x500)
LCM = 2417141300000/2500
LCM = 966856520
Thus, we can understand that the LCM of 835,280,290,230,155 is 966856520.
