The LCM of 800,915,571,834,680 is 197533567200.
Find LCM of 800,915,571,834,680 with Prime Factorization
| 2 | 800, 915, 571, 834, 680 |
| 2 | 400, 915, 571, 417, 340 |
| 2 | 200, 915, 571, 417, 170 |
| 3 | 100, 915, 571, 417, 85 |
| 5 | 100, 305, 571, 139, 85 |
| 20, 61, 571, 139, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 20 x 61 x 571 x 139 x 17 = 197533567200
Therefore, the lowest common multiple of 800,915,571,834,680 is 197533567200.
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 915 x 571 x 834 x 680 = 237040280640000
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
915 : 1, 3, 5, 15, 61, 183, 305, 915
571 : 1, 571
834 : 1, 2, 3, 6, 139, 278, 417, 834
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,915,571,834,680, is 1.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
915:3x 5x 61
571:571
834:2x 3x 139
680:2x 2x 2x 5x 17
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 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 237040280640000/(1x1200)
LCM = 237040280640000/1200
LCM = 197533567200
Thus, we can understand that the LCM of 800,915,571,834,680 is 197533567200.
