Given numbers are 705,121,165,230
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,121,165,230 is 3924030.
Find LCM of 705,121,165,230 with Prime Factorization
| 3 | 705, 121, 165, 230 |
| 5 | 235, 121, 55, 230 |
| 11 | 47, 121, 11, 46 |
| 47, 1, 11, 46 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 47 x 1 x 11 x 46 = 3924030
Therefore, the lowest common multiple of 705,121,165,230 is 3924030.
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.
705 x 121 x 165 x 230 = 3237324750
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
121 : 1, 11, 121
165 : 1, 3, 5, 11, 15, 33, 55, 165
230 : 1, 2, 5, 10, 23, 46, 115, 230
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,121,165,230, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
121:11x 11
165:3x 5x 11
230:2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11 = 825
Therefore, the value for common factors is 825.
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 = 3237324750/(1x825)
LCM = 3237324750/825
LCM = 3924030
Thus, we can understand that the LCM of 705,121,165,230 is 3924030.
