Given numbers are 585,865,905,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 585,865,905,450 is 183181050.
Find LCM of 585,865,905,450 with Prime Factorization
| 3 | 585, 865, 905, 450 |
| 3 | 195, 865, 905, 150 |
| 5 | 65, 865, 905, 50 |
| 13, 173, 181, 10 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 173 x 181 x 10 = 183181050
Therefore, the lowest common multiple of 585,865,905,450 is 183181050.
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.
585 x 865 x 905 x 450 = 206078681250
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.
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
865 : 1, 5, 173, 865
905 : 1, 5, 181, 905
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,865,905,450, is 5.
Now, the common factors can be found like this.
585:3x 3x 5x 13
865:5x 173
905:5x 181
450:2x 3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 206078681250/(5x225)
LCM = 206078681250/1125
LCM = 183181050
Thus, we can understand that the LCM of 585,865,905,450 is 183181050.
