Given numbers are 90,81,95,15,323
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 90,81,95,15,323 is 261630.
Find LCM of 90,81,95,15,323 with Prime Factorization
| 3 | 90, 81, 95, 15, 323 |
| 3 | 30, 27, 95, 5, 323 |
| 5 | 10, 9, 95, 5, 323 |
| 19 | 2, 9, 19, 1, 323 |
| 2, 9, 1, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 2 x 9 x 1 x 1 x 17 = 261630
Therefore, the lowest common multiple of 90,81,95,15,323 is 261630.
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.
90 x 81 x 95 x 15 x 323 = 3355404750
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.
90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
81 : 1, 3, 9, 27, 81
95 : 1, 5, 19, 95
15 : 1, 3, 5, 15
323 : 1, 17, 19, 323
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 90,81,95,15,323, is 1.
Now, the common factors can be found like this.
90:2x 3x 3x 5
81:3x 3x 3x 3
95:5x 19
15:3x 5
323:17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 5x 19 = 12825
Therefore, the value for common factors is 12825.
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 = 3355404750/(1x12825)
LCM = 3355404750/12825
LCM = 261630
Thus, we can understand that the LCM of 90,81,95,15,323 is 261630.
