Given numbers are 180,196,647,858,205
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,196,647,858,205 is 33457444020.
Find LCM of 180,196,647,858,205 with Prime Factorization
| 2 | 180, 196, 647, 858, 205 |
| 2 | 90, 98, 647, 429, 205 |
| 3 | 45, 49, 647, 429, 205 |
| 5 | 15, 49, 647, 143, 205 |
| 3, 49, 647, 143, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 3 x 49 x 647 x 143 x 41 = 33457444020
Therefore, the lowest common multiple of 180,196,647,858,205 is 33457444020.
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.
180 x 196 x 647 x 858 x 205 = 4014893282400
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
647 : 1, 647
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
205 : 1, 5, 41, 205
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,196,647,858,205, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
196:2x 2x 7x 7
647:647
858:2x 3x 11x 13
205:5x 41
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 = 4014893282400/(1x120)
LCM = 4014893282400/120
LCM = 33457444020
Thus, we can understand that the LCM of 180,196,647,858,205 is 33457444020.
