Given numbers are 824,206,391,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,206,391,874 is 6121496.
Find LCM of 824,206,391,874 with Prime Factorization
| 2 | 824, 206, 391, 874 |
| 23 | 412, 103, 391, 437 |
| 103 | 412, 103, 17, 19 |
| 4, 1, 17, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 103 x 4 x 1 x 17 x 19 = 6121496
Therefore, the lowest common multiple of 824,206,391,874 is 6121496.
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.
824 x 206 x 391 x 874 = 58007296096
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
206 : 1, 2, 103, 206
391 : 1, 17, 23, 391
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,206,391,874, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
206:2x 103
391:17x 23
874:2x 19x 23
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 23x 103 = 9476
Therefore, the value for common factors is 9476.
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 = 58007296096/(1x9476)
LCM = 58007296096/9476
LCM = 6121496
Thus, we can understand that the LCM of 824,206,391,874 is 6121496.
