Given numbers are 753,405,855,144,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 753,405,855,144,745 is 4604564880.
Find LCM of 753,405,855,144,745 with Prime Factorization
| 3 | 753, 405, 855, 144, 745 |
| 3 | 251, 135, 285, 48, 745 |
| 5 | 251, 45, 95, 16, 745 |
| 251, 9, 19, 16, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 251 x 9 x 19 x 16 x 149 = 4604564880
Therefore, the lowest common multiple of 753,405,855,144,745 is 4604564880.
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.
753 x 405 x 855 x 144 x 745 = 27972731646000
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.
753 : 1, 3, 251, 753
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,405,855,144,745, is 1.
Now, the common factors can be found like this.
753:3x 251
405:3x 3x 3x 3x 5
855:3x 3x 5x 19
144:2x 2x 2x 2x 3x 3
745:5x 149
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 3x 3x 3x 5x 5 = 6075
Therefore, the value for common factors is 6075.
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 = 27972731646000/(1x6075)
LCM = 27972731646000/6075
LCM = 4604564880
Thus, we can understand that the LCM of 753,405,855,144,745 is 4604564880.
