Given numbers are 189,238,145,806,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,238,145,806,105 is 375503310.
Find LCM of 189,238,145,806,105 with Prime Factorization
| 2 | 189, 238, 145, 806, 105 |
| 3 | 189, 119, 145, 403, 105 |
| 5 | 63, 119, 145, 403, 35 |
| 7 | 63, 119, 29, 403, 7 |
| 9, 17, 29, 403, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 9 x 17 x 29 x 403 x 1 = 375503310
Therefore, the lowest common multiple of 189,238,145,806,105 is 375503310.
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.
189 x 238 x 145 x 806 x 105 = 551989865700
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
238 : 1, 2, 7, 14, 17, 34, 119, 238
145 : 1, 5, 29, 145
806 : 1, 2, 13, 26, 31, 62, 403, 806
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,238,145,806,105, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
238:2x 7x 17
145:5x 29
806:2x 13x 31
105:3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7x 7 = 1470
Therefore, the value for common factors is 1470.
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 = 551989865700/(1x1470)
LCM = 551989865700/1470
LCM = 375503310
Thus, we can understand that the LCM of 189,238,145,806,105 is 375503310.
