Given numbers are 331,156,915,418,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,156,915,418,351 is 29623831380.
Find LCM of 331,156,915,418,351 with Prime Factorization
| 2 | 331, 156, 915, 418, 351 |
| 3 | 331, 78, 915, 209, 351 |
| 13 | 331, 26, 305, 209, 117 |
| 331, 2, 305, 209, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 331 x 2 x 305 x 209 x 9 = 29623831380
Therefore, the lowest common multiple of 331,156,915,418,351 is 29623831380.
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.
331 x 156 x 915 x 418 x 351 = 6931976542920
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.
331 : 1, 331
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
915 : 1, 3, 5, 15, 61, 183, 305, 915
418 : 1, 2, 11, 19, 22, 38, 209, 418
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,156,915,418,351, is 1.
Now, the common factors can be found like this.
331:331
156:2x 2x 3x 13
915:3x 5x 61
418:2x 11x 19
351:3x 3x 3x 13
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 13 = 234
Therefore, the value for common factors is 234.
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 = 6931976542920/(1x234)
LCM = 6931976542920/234
LCM = 29623831380
Thus, we can understand that the LCM of 331,156,915,418,351 is 29623831380.
