The LCM of 18,33,57,80,880 is 150480.
Find LCM of 18,33,57,80,880 with Prime Factorization
| 2 | 18, 33, 57, 80, 880 |
| 2 | 9, 33, 57, 40, 440 |
| 2 | 9, 33, 57, 20, 220 |
| 2 | 9, 33, 57, 10, 110 |
| 3 | 9, 33, 57, 5, 55 |
| 5 | 3, 11, 19, 5, 55 |
| 11 | 3, 11, 19, 1, 11 |
| 3, 1, 19, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 11 x 3 x 1 x 19 x 1 x 1 = 150480
Therefore, the lowest common multiple of 18,33,57,80,880 is 150480.
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.
18 x 33 x 57 x 80 x 880 = 2383603200
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.
18 : 1, 2, 3, 6, 9, 18
33 : 1, 3, 11, 33
57 : 1, 3, 19, 57
80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,33,57,80,880, is 1.
Now, the common factors can be found like this.
18:2x 3x 3
33:3x 11
57:3x 19
80:2x 2x 2x 2x 5
880:2x 2x 2x 2x 5x 11
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 2x 2x 2x 3x 3x 5x 11 = 15840
Therefore, the value for common factors is 15840.
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 = 2383603200/(1x15840)
LCM = 2383603200/15840
LCM = 150480
Thus, we can understand that the LCM of 18,33,57,80,880 is 150480.
