Given numbers are 165,603,205,461
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,603,205,461 is 626851665.
Find LCM of 165,603,205,461 with Prime Factorization
| 3 | 165, 603, 205, 461 |
| 5 | 55, 201, 205, 461 |
| 11, 201, 41, 461 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 201 x 41 x 461 = 626851665
Therefore, the lowest common multiple of 165,603,205,461 is 626851665.
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.
165 x 603 x 205 x 461 = 9402774975
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
603 : 1, 3, 9, 67, 201, 603
205 : 1, 5, 41, 205
461 : 1, 461
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,603,205,461, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
603:3x 3x 67
205:5x 41
461:461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 9402774975/(1x15)
LCM = 9402774975/15
LCM = 626851665
Thus, we can understand that the LCM of 165,603,205,461 is 626851665.
