Given numbers are 138,197,124,928,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,197,124,928,872 is 42623733216.
Find LCM of 138,197,124,928,872 with Prime Factorization
| 2 | 138, 197, 124, 928, 872 |
| 2 | 69, 197, 62, 464, 436 |
| 2 | 69, 197, 31, 232, 218 |
| 69, 197, 31, 116, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 69 x 197 x 31 x 116 x 109 = 42623733216
Therefore, the lowest common multiple of 138,197,124,928,872 is 42623733216.
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.
138 x 197 x 124 x 928 x 872 = 2727918925824
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
197 : 1, 197
124 : 1, 2, 4, 31, 62, 124
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,197,124,928,872, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
197:197
124:2x 2x 31
928:2x 2x 2x 2x 2x 29
872:2x 2x 2x 109
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 2 = 64
Therefore, the value for common factors is 64.
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 = 2727918925824/(1x64)
LCM = 2727918925824/64
LCM = 42623733216
Thus, we can understand that the LCM of 138,197,124,928,872 is 42623733216.
