Given numbers are 181,690,230,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 181,690,230,285 is 2372910.
Find LCM of 181,690,230,285 with Prime Factorization
| 2 | 181, 690, 230, 285 |
| 3 | 181, 345, 115, 285 |
| 5 | 181, 115, 115, 95 |
| 23 | 181, 23, 23, 19 |
| 181, 1, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 181 x 1 x 1 x 19 = 2372910
Therefore, the lowest common multiple of 181,690,230,285 is 2372910.
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.
181 x 690 x 230 x 285 = 8186539500
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.
181 : 1, 181
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
230 : 1, 2, 5, 10, 23, 46, 115, 230
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 181,690,230,285, is 1.
Now, the common factors can be found like this.
181:181
690:2x 3x 5x 23
230:2x 5x 23
285:3x 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 3x 5x 5x 23 = 3450
Therefore, the value for common factors is 3450.
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 = 8186539500/(1x3450)
LCM = 8186539500/3450
LCM = 2372910
Thus, we can understand that the LCM of 181,690,230,285 is 2372910.
