Given numbers are 359,305,323,644,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 359,305,323,644,391 is 22776273940.
Find LCM of 359,305,323,644,391 with Prime Factorization
| 17 | 359, 305, 323, 644, 391 |
| 23 | 359, 305, 19, 644, 23 |
| 359, 305, 19, 28, 1 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 359 x 305 x 19 x 28 x 1 = 22776273940
Therefore, the lowest common multiple of 359,305,323,644,391 is 22776273940.
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.
359 x 305 x 323 x 644 x 391 = 8905523110540
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.
359 : 1, 359
305 : 1, 5, 61, 305
323 : 1, 17, 19, 323
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 359,305,323,644,391, is 1.
Now, the common factors can be found like this.
359:359
305:5x 61
323:17x 19
644:2x 2x 7x 23
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
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 = 8905523110540/(1x391)
LCM = 8905523110540/391
LCM = 22776273940
Thus, we can understand that the LCM of 359,305,323,644,391 is 22776273940.
