Find LCM of 368,920,836,345 with Prime Factorization
| 2 | 368, 920, 836, 345 |
| 2 | 184, 460, 418, 345 |
| 2 | 92, 230, 209, 345 |
| 5 | 46, 115, 209, 345 |
| 23 | 46, 23, 209, 69 |
| 2, 1, 209, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 2 x 1 x 209 x 3 = 1153680
Therefore, the lowest common multiple of 368,920,836,345 is 1153680.
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.
368 x 920 x 836 x 345 = 97647475200
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,920,836,345, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
920:2x 2x 2x 5x 23
836:2x 2x 11x 19
345:3x 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 2x 2x 5x 23x 23 = 84640
Therefore, the value for common factors is 84640.
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 = 97647475200/(1x84640)
LCM = 97647475200/84640
LCM = 1153680
Thus, we can understand that the LCM of 368,920,836,345 is 1153680.
