Given numbers are 99,54,20,81,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 99,54,20,81,450 is 89100.
Find LCM of 99,54,20,81,450 with Prime Factorization
| 2 | 99, 54, 20, 81, 450 |
| 3 | 99, 27, 10, 81, 225 |
| 3 | 33, 9, 10, 27, 75 |
| 3 | 11, 3, 10, 9, 25 |
| 5 | 11, 1, 10, 3, 25 |
| 11, 1, 2, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 11 x 1 x 2 x 3 x 5 = 89100
Therefore, the lowest common multiple of 99,54,20,81,450 is 89100.
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.
99 x 54 x 20 x 81 x 450 = 3897234000
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.
99 : 1, 3, 9, 11, 33, 99
54 : 1, 2, 3, 6, 9, 18, 27, 54
20 : 1, 2, 4, 5, 10, 20
81 : 1, 3, 9, 27, 81
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 99,54,20,81,450, is 1.
Now, the common factors can be found like this.
99:3x 3x 11
54:2x 3x 3x 3
20:2x 2x 5
81:3x 3x 3x 3
450:2x 3x 3x 5x 5
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 3x 3x 3x 3x 3x 5 = 43740
Therefore, the value for common factors is 43740.
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 = 3897234000/(1x43740)
LCM = 3897234000/43740
LCM = 89100
Thus, we can understand that the LCM of 99,54,20,81,450 is 89100.
