Find LCM of 678,923,800,320 with Prime Factorization
| 2 | 678, 923, 800, 320 |
| 2 | 339, 923, 400, 160 |
| 2 | 339, 923, 200, 80 |
| 2 | 339, 923, 100, 40 |
| 2 | 339, 923, 50, 20 |
| 5 | 339, 923, 25, 10 |
| 339, 923, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 339 x 923 x 5 x 2 = 500635200
Therefore, the lowest common multiple of 678,923,800,320 is 500635200.
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.
678 x 923 x 800 x 320 = 160203264000
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
923 : 1, 13, 71, 923
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,923,800,320, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
923:13x 71
800:2x 2x 2x 2x 2x 5x 5
320:2x 2x 2x 2x 2x 2x 5
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 = 160203264000/(1x320)
LCM = 160203264000/320
LCM = 500635200
Thus, we can understand that the LCM of 678,923,800,320 is 500635200.
