Find LCM of 261,510,408,479,985 with Prime Factorization
| 2 | 261, 510, 408, 479, 985 |
| 3 | 261, 255, 204, 479, 985 |
| 5 | 87, 85, 68, 479, 985 |
| 17 | 87, 17, 68, 479, 197 |
| 87, 1, 4, 479, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 87 x 1 x 4 x 479 x 197 = 16747545240
Therefore, the lowest common multiple of 261,510,408,479,985 is 16747545240.
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.
261 x 510 x 408 x 479 x 985 = 25623744217200
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.
261 : 1, 3, 9, 29, 87, 261
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
479 : 1, 479
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,510,408,479,985, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
510:2x 3x 5x 17
408:2x 2x 2x 3x 17
479:479
985:5x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 17 = 1530
Therefore, the value for common factors is 1530.
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 = 25623744217200/(1x1530)
LCM = 25623744217200/1530
LCM = 16747545240
Thus, we can understand that the LCM of 261,510,408,479,985 is 16747545240.
