Given numbers are 444,405,555,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 444,405,555,646 is 19360620.
Find LCM of 444,405,555,646 with Prime Factorization
| 2 | 444, 405, 555, 646 |
| 3 | 222, 405, 555, 323 |
| 5 | 74, 135, 185, 323 |
| 37 | 74, 27, 37, 323 |
| 2, 27, 1, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 2 x 27 x 1 x 323 = 19360620
Therefore, the lowest common multiple of 444,405,555,646 is 19360620.
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.
444 x 405 x 555 x 646 = 64470864600
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.
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
555 : 1, 3, 5, 15, 37, 111, 185, 555
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 444,405,555,646, is 1.
Now, the common factors can be found like this.
444:2x 2x 3x 37
405:3x 3x 3x 3x 5
555:3x 5x 37
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 37 = 3330
Therefore, the value for common factors is 3330.
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 = 64470864600/(1x3330)
LCM = 64470864600/3330
LCM = 19360620
Thus, we can understand that the LCM of 444,405,555,646 is 19360620.
