Find LCM of 800,838,864,670 with Prime Factorization
| 2 | 800, 838, 864, 670 |
| 2 | 400, 419, 432, 335 |
| 2 | 200, 419, 216, 335 |
| 2 | 100, 419, 108, 335 |
| 2 | 50, 419, 54, 335 |
| 5 | 25, 419, 27, 335 |
| 5, 419, 27, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 5 x 419 x 27 x 67 = 606376800
Therefore, the lowest common multiple of 800,838,864,670 is 606376800.
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.
800 x 838 x 864 x 670 = 388081152000
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.
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
838 : 1, 2, 419, 838
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
670 : 1, 2, 5, 10, 67, 134, 335, 670
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,838,864,670, is 2.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
838:2x 419
864:2x 2x 2x 2x 2x 3x 3x 3
670:2x 5x 67
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 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 388081152000/(2x320)
LCM = 388081152000/640
LCM = 606376800
Thus, we can understand that the LCM of 800,838,864,670 is 606376800.
