Given numbers are 357,627,399,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,627,399,990 is 2238390.
Find LCM of 357,627,399,990 with Prime Factorization
| 3 | 357, 627, 399, 990 |
| 7 | 119, 209, 133, 330 |
| 11 | 17, 209, 19, 330 |
| 19 | 17, 19, 19, 30 |
| 17, 1, 1, 30 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 19 x 17 x 1 x 1 x 30 = 2238390
Therefore, the lowest common multiple of 357,627,399,990 is 2238390.
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.
357 x 627 x 399 x 990 = 88418643390
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
627 : 1, 3, 11, 19, 33, 57, 209, 627
399 : 1, 3, 7, 19, 21, 57, 133, 399
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 357,627,399,990, is 3.
Now, the common factors can be found like this.
357:3x 7x 17
627:3x 11x 19
399:3x 7x 19
990:2x 3x 3x 5x 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 3x 7x 11x 19 = 13167
Therefore, the value for common factors is 13167.
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 = 88418643390/(3x13167)
LCM = 88418643390/39501
LCM = 2238390
Thus, we can understand that the LCM of 357,627,399,990 is 2238390.
