Given numbers are 678,309,791,450,844
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,309,791,450,844 is 15471722700.
Find LCM of 678,309,791,450,844 with Prime Factorization
| 2 | 678, 309, 791, 450, 844 |
| 3 | 339, 309, 791, 225, 422 |
| 113 | 113, 103, 791, 75, 422 |
| 1, 103, 7, 75, 422 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 113 x 1 x 103 x 7 x 75 x 422 = 15471722700
Therefore, the lowest common multiple of 678,309,791,450,844 is 15471722700.
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.
678 x 309 x 791 x 450 x 844 = 62938967943600
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
309 : 1, 3, 103, 309
791 : 1, 7, 113, 791
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
844 : 1, 2, 4, 211, 422, 844
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,309,791,450,844, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
309:3x 103
791:7x 113
450:2x 3x 3x 5x 5
844:2x 2x 211
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 3x 3x 113 = 4068
Therefore, the value for common factors is 4068.
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 = 62938967943600/(1x4068)
LCM = 62938967943600/4068
LCM = 15471722700
Thus, we can understand that the LCM of 678,309,791,450,844 is 15471722700.
