Find LCM of 111,345,251,768,920 with Prime Factorization
| 2 | 111, 345, 251, 768, 920 |
| 2 | 111, 345, 251, 384, 460 |
| 2 | 111, 345, 251, 192, 230 |
| 3 | 111, 345, 251, 96, 115 |
| 5 | 37, 115, 251, 32, 115 |
| 23 | 37, 23, 251, 32, 23 |
| 37, 1, 251, 32, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 23 x 37 x 1 x 251 x 32 x 1 = 820227840
Therefore, the lowest common multiple of 111,345,251,768,920 is 820227840.
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.
111 x 345 x 251 x 768 x 920 = 6791486515200
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.
111 : 1, 3, 37, 111
345 : 1, 3, 5, 15, 23, 69, 115, 345
251 : 1, 251
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,345,251,768,920, is 1.
Now, the common factors can be found like this.
111:3x 37
345:3x 5x 23
251:251
768:2x 2x 2x 2x 2x 2x 2x 2x 3
920:2x 2x 2x 5x 23
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 5x 23 = 8280
Therefore, the value for common factors is 8280.
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 = 6791486515200/(1x8280)
LCM = 6791486515200/8280
LCM = 820227840
Thus, we can understand that the LCM of 111,345,251,768,920 is 820227840.
