Given numbers are 473,691,397,165,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,691,397,165,231 is 13624450455.
Find LCM of 473,691,397,165,231 with Prime Factorization
| 3 | 473, 691, 397, 165, 231 |
| 11 | 473, 691, 397, 55, 77 |
| 43, 691, 397, 5, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 43 x 691 x 397 x 5 x 7 = 13624450455
Therefore, the lowest common multiple of 473,691,397,165,231 is 13624450455.
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.
473 x 691 x 397 x 165 x 231 = 4945675515165
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.
473 : 1, 11, 43, 473
691 : 1, 691
397 : 1, 397
165 : 1, 3, 5, 11, 15, 33, 55, 165
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,691,397,165,231, is 1.
Now, the common factors can be found like this.
473:11x 43
691:691
397:397
165:3x 5x 11
231:3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11 = 363
Therefore, the value for common factors is 363.
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 = 4945675515165/(1x363)
LCM = 4945675515165/363
LCM = 13624450455
Thus, we can understand that the LCM of 473,691,397,165,231 is 13624450455.
