Given numbers are 391,244,116,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,244,116,485 is 1341857260.
Find LCM of 391,244,116,485 with Prime Factorization
| 2 | 391, 244, 116, 485 |
| 2 | 391, 122, 58, 485 |
| 391, 61, 29, 485 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 391 x 61 x 29 x 485 = 1341857260
Therefore, the lowest common multiple of 391,244,116,485 is 1341857260.
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.
391 x 244 x 116 x 485 = 5367429040
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.
391 : 1, 17, 23, 391
244 : 1, 2, 4, 61, 122, 244
116 : 1, 2, 4, 29, 58, 116
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,244,116,485, is 1.
Now, the common factors can be found like this.
391:17x 23
244:2x 2x 61
116:2x 2x 29
485:5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 5367429040/(1x4)
LCM = 5367429040/4
LCM = 1341857260
Thus, we can understand that the LCM of 391,244,116,485 is 1341857260.
