The LCM of 455,510,728,789 is 48823320.
Find LCM of 455,510,728,789 with Prime Factorization
| 2 | 455, 510, 728, 789 |
| 3 | 455, 255, 364, 789 |
| 5 | 455, 85, 364, 263 |
| 7 | 91, 17, 364, 263 |
| 13 | 13, 17, 52, 263 |
| 1, 17, 4, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 1 x 17 x 4 x 263 = 48823320
Therefore, the lowest common multiple of 455,510,728,789 is 48823320.
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.
455 x 510 x 728 x 789 = 133287663600
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,510,728,789, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
510:2x 3x 5x 17
728:2x 2x 2x 7x 13
789:3x 263
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 5x 7x 13 = 2730
Therefore, the value for common factors is 2730.
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 = 133287663600/(1x2730)
LCM = 133287663600/2730
LCM = 48823320
Thus, we can understand that the LCM of 455,510,728,789 is 48823320.
