Given numbers are 355,545,189,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,545,189,109 is 7313355.
Find LCM of 355,545,189,109 with Prime Factorization
| 5 | 355, 545, 189, 109 |
| 109 | 71, 109, 189, 109 |
| 71, 1, 189, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 109 x 71 x 1 x 189 x 1 = 7313355
Therefore, the lowest common multiple of 355,545,189,109 is 7313355.
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.
355 x 545 x 189 x 109 = 3985778475
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.
355 : 1, 5, 71, 355
545 : 1, 5, 109, 545
189 : 1, 3, 7, 9, 21, 27, 63, 189
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,545,189,109, is 1.
Now, the common factors can be found like this.
355:5x 71
545:5x 109
189:3x 3x 3x 7
109:109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 109 = 545
Therefore, the value for common factors is 545.
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 = 3985778475/(1x545)
LCM = 3985778475/545
LCM = 7313355
Thus, we can understand that the LCM of 355,545,189,109 is 7313355.
