The LCM of 384,885,685,390 is 201751680.
Find LCM of 384,885,685,390 with Prime Factorization
| 2 | 384, 885, 685, 390 |
| 3 | 192, 885, 685, 195 |
| 5 | 64, 295, 685, 65 |
| 64, 59, 137, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 64 x 59 x 137 x 13 = 201751680
Therefore, the lowest common multiple of 384,885,685,390 is 201751680.
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.
384 x 885 x 685 x 390 = 90788256000
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.
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
885 : 1, 3, 5, 15, 59, 177, 295, 885
685 : 1, 5, 137, 685
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 384,885,685,390, is 1.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
885:3x 5x 59
685:5x 137
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 90788256000/(1x450)
LCM = 90788256000/450
LCM = 201751680
Thus, we can understand that the LCM of 384,885,685,390 is 201751680.
