Find LCM of 861,840,551,500,384 with Prime Factorization
| 2 | 861, 840, 551, 500, 384 |
| 2 | 861, 420, 551, 250, 192 |
| 2 | 861, 210, 551, 125, 96 |
| 3 | 861, 105, 551, 125, 48 |
| 5 | 287, 35, 551, 125, 16 |
| 7 | 287, 7, 551, 25, 16 |
| 41, 1, 551, 25, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 41 x 1 x 551 x 25 x 16 = 7590576000
Therefore, the lowest common multiple of 861,840,551,500,384 is 7590576000.
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.
861 x 840 x 551 x 500 x 384 = 76513006080000
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
551 : 1, 19, 29, 551
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,840,551,500,384, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
840:2x 2x 2x 3x 5x 7
551:19x 29
500:2x 2x 5x 5x 5
384:2x 2x 2x 2x 2x 2x 2x 3
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 3x 3x 5x 7 = 10080
Therefore, the value for common factors is 10080.
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 = 76513006080000/(1x10080)
LCM = 76513006080000/10080
LCM = 7590576000
Thus, we can understand that the LCM of 861,840,551,500,384 is 7590576000.
