Given numbers are 338,494,456,442,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,494,456,442,361 is 24891672.
Find LCM of 338,494,456,442,361 with Prime Factorization
| 2 | 338, 494, 456, 442, 361 |
| 13 | 169, 247, 228, 221, 361 |
| 19 | 13, 19, 228, 17, 361 |
| 13, 1, 12, 17, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 13 x 1 x 12 x 17 x 19 = 24891672
Therefore, the lowest common multiple of 338,494,456,442,361 is 24891672.
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.
338 x 494 x 456 x 442 x 361 = 12148928136384
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.
338 : 1, 2, 13, 26, 169, 338
494 : 1, 2, 13, 19, 26, 38, 247, 494
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
442 : 1, 2, 13, 17, 26, 34, 221, 442
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,494,456,442,361, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
494:2x 13x 19
456:2x 2x 2x 3x 19
442:2x 13x 17
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 13x 13x 19x 19 = 488072
Therefore, the value for common factors is 488072.
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 = 12148928136384/(1x488072)
LCM = 12148928136384/488072
LCM = 24891672
Thus, we can understand that the LCM of 338,494,456,442,361 is 24891672.
