Find LCM of 336,621,667,945 with Prime Factorization
| 3 | 336, 621, 667, 945 |
| 3 | 112, 207, 667, 315 |
| 3 | 112, 69, 667, 105 |
| 7 | 112, 23, 667, 35 |
| 23 | 16, 23, 667, 5 |
| 16, 1, 29, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 23 x 16 x 1 x 29 x 5 = 10085040
Therefore, the lowest common multiple of 336,621,667,945 is 10085040.
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.
336 x 621 x 667 x 945 = 131519006640
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.
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
621 : 1, 3, 9, 23, 27, 69, 207, 621
667 : 1, 23, 29, 667
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 336,621,667,945, is 1.
Now, the common factors can be found like this.
336:2x 2x 2x 2x 3x 7
621:3x 3x 3x 23
667:23x 29
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7x 23 = 13041
Therefore, the value for common factors is 13041.
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 = 131519006640/(1x13041)
LCM = 131519006640/13041
LCM = 10085040
Thus, we can understand that the LCM of 336,621,667,945 is 10085040.
