Given numbers are 815,921,904,600
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,921,904,600 is 3392779800.
Find LCM of 815,921,904,600 with Prime Factorization
| 2 | 815, 921, 904, 600 |
| 2 | 815, 921, 452, 300 |
| 2 | 815, 921, 226, 150 |
| 3 | 815, 921, 113, 75 |
| 5 | 815, 307, 113, 25 |
| 163, 307, 113, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 163 x 307 x 113 x 5 = 3392779800
Therefore, the lowest common multiple of 815,921,904,600 is 3392779800.
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.
815 x 921 x 904 x 600 = 407133576000
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.
815 : 1, 5, 163, 815
921 : 1, 3, 307, 921
904 : 1, 2, 4, 8, 113, 226, 452, 904
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,921,904,600, is 1.
Now, the common factors can be found like this.
815:5x 163
921:3x 307
904:2x 2x 2x 113
600:2x 2x 2x 3x 5x 5
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 407133576000/(1x120)
LCM = 407133576000/120
LCM = 3392779800
Thus, we can understand that the LCM of 815,921,904,600 is 3392779800.
