Given numbers are 38,54,36,56,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 38,54,36,56,987 is 1350216.
Find LCM of 38,54,36,56,987 with Prime Factorization
| 2 | 38, 54, 36, 56, 987 |
| 2 | 19, 27, 18, 28, 987 |
| 3 | 19, 27, 9, 14, 987 |
| 3 | 19, 3, 9, 14, 329 |
| 7 | 19, 1, 3, 14, 329 |
| 19, 1, 3, 2, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 19 x 1 x 3 x 2 x 47 = 1350216
Therefore, the lowest common multiple of 38,54,36,56,987 is 1350216.
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 54 x 36 x 56 x 987 = 4083053184
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
54 : 1, 2, 3, 6, 9, 18, 27, 54
36 : 1, 2, 3, 4, 6, 9, 12, 18, 36
56 : 1, 2, 4, 7, 8, 14, 28, 56
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 38,54,36,56,987, is 1.
Now, the common factors can be found like this.
38:2x 19
54:2x 3x 3x 3
36:2x 2x 3x 3
56:2x 2x 2x 7
987:3x 7x 47
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 3x 3x 3x 7 = 3024
Therefore, the value for common factors is 3024.
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 = 4083053184/(1x3024)
LCM = 4083053184/3024
LCM = 1350216
Thus, we can understand that the LCM of 38,54,36,56,987 is 1350216.
