Given numbers are 328,736,644,142,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 328,736,644,142,361 is 5414087392.
Find LCM of 328,736,644,142,361 with Prime Factorization
| 2 | 328, 736, 644, 142, 361 |
| 2 | 164, 368, 322, 71, 361 |
| 2 | 82, 184, 161, 71, 361 |
| 23 | 41, 92, 161, 71, 361 |
| 41, 4, 7, 71, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 23 x 41 x 4 x 7 x 71 x 361 = 5414087392
Therefore, the lowest common multiple of 328,736,644,142,361 is 5414087392.
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.
328 x 736 x 644 x 142 x 361 = 7969536641024
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
142 : 1, 2, 71, 142
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,736,644,142,361, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
736:2x 2x 2x 2x 2x 23
644:2x 2x 7x 23
142:2x 71
361:19x 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 2x 2x 2x 2x 2x 23 = 1472
Therefore, the value for common factors is 1472.
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 = 7969536641024/(1x1472)
LCM = 7969536641024/1472
LCM = 5414087392
Thus, we can understand that the LCM of 328,736,644,142,361 is 5414087392.
