Given numbers are 424,687,545,800,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 424,687,545,800,421 is 1336691503200.
Find LCM of 424,687,545,800,421 with Prime Factorization
| 2 | 424, 687, 545, 800, 421 |
| 2 | 212, 687, 545, 400, 421 |
| 2 | 106, 687, 545, 200, 421 |
| 5 | 53, 687, 545, 100, 421 |
| 53, 687, 109, 20, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 53 x 687 x 109 x 20 x 421 = 1336691503200
Therefore, the lowest common multiple of 424,687,545,800,421 is 1336691503200.
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.
424 x 687 x 545 x 800 x 421 = 53467660128000
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.
424 : 1, 2, 4, 8, 53, 106, 212, 424
687 : 1, 3, 229, 687
545 : 1, 5, 109, 545
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,687,545,800,421, is 1.
Now, the common factors can be found like this.
424:2x 2x 2x 53
687:3x 229
545:5x 109
800:2x 2x 2x 2x 2x 5x 5
421:421
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 5 = 40
Therefore, the value for common factors is 40.
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 = 53467660128000/(1x40)
LCM = 53467660128000/40
LCM = 1336691503200
Thus, we can understand that the LCM of 424,687,545,800,421 is 1336691503200.
