Given numbers are 38,78,12,33,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 38,78,12,33,494 is 32604.
Find LCM of 38,78,12,33,494 with Prime Factorization
| 2 | 38, 78, 12, 33, 494 |
| 3 | 19, 39, 6, 33, 247 |
| 13 | 19, 13, 2, 11, 247 |
| 19 | 19, 1, 2, 11, 19 |
| 1, 1, 2, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 1 x 1 x 2 x 11 x 1 = 32604
Therefore, the lowest common multiple of 38,78,12,33,494 is 32604.
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.
38 x 78 x 12 x 33 x 494 = 579829536
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.
38 : 1, 2, 19, 38
78 : 1, 2, 3, 6, 13, 26, 39, 78
12 : 1, 2, 3, 4, 6, 12
33 : 1, 3, 11, 33
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 38,78,12,33,494, is 1.
Now, the common factors can be found like this.
38:2x 19
78:2x 3x 13
12:2x 2x 3
33:3x 11
494:2x 13x 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 2x 2x 3x 3x 13x 19 = 17784
Therefore, the value for common factors is 17784.
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 = 579829536/(1x17784)
LCM = 579829536/17784
LCM = 32604
Thus, we can understand that the LCM of 38,78,12,33,494 is 32604.
