Given numbers are 218,358,470,846
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,358,470,846 is 82531530.
Find LCM of 218,358,470,846 with Prime Factorization
| 2 | 218, 358, 470, 846 |
| 47 | 109, 179, 235, 423 |
| 109, 179, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 47 x 109 x 179 x 5 x 9 = 82531530
Therefore, the lowest common multiple of 218,358,470,846 is 82531530.
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.
218 x 358 x 470 x 846 = 31031855280
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.
218 : 1, 2, 109, 218
358 : 1, 2, 179, 358
470 : 1, 2, 5, 10, 47, 94, 235, 470
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,358,470,846, is 2.
Now, the common factors can be found like this.
218:2x 109
358:2x 179
470:2x 5x 47
846:2x 3x 3x 47
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 47 = 188
Therefore, the value for common factors is 188.
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 = 31031855280/(2x188)
LCM = 31031855280/376
LCM = 82531530
Thus, we can understand that the LCM of 218,358,470,846 is 82531530.
