The LCM of 828,800,315,769 is 891424800.
Find LCM of 828,800,315,769 with Prime Factorization
| 2 | 828, 800, 315, 769 |
| 2 | 414, 400, 315, 769 |
| 3 | 207, 200, 315, 769 |
| 3 | 69, 200, 105, 769 |
| 5 | 23, 200, 35, 769 |
| 23, 40, 7, 769 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 23 x 40 x 7 x 769 = 891424800
Therefore, the lowest common multiple of 828,800,315,769 is 891424800.
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.
828 x 800 x 315 x 769 = 160456464000
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,800,315,769, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
800:2x 2x 2x 2x 2x 5x 5
315:3x 3x 5x 7
769:769
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 160456464000/(1x180)
LCM = 160456464000/180
LCM = 891424800
Thus, we can understand that the LCM of 828,800,315,769 is 891424800.
