Find LCM of 990,715,273,399 with Prime Factorization
| 3 | 990, 715, 273, 399 |
| 5 | 330, 715, 91, 133 |
| 7 | 66, 143, 91, 133 |
| 11 | 66, 143, 13, 19 |
| 13 | 6, 13, 13, 19 |
| 6, 1, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 11 x 13 x 6 x 1 x 1 x 19 = 1711710
Therefore, the lowest common multiple of 990,715,273,399 is 1711710.
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.
990 x 715 x 273 x 399 = 77103976950
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.
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
273 : 1, 3, 7, 13, 21, 39, 91, 273
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,715,273,399, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
715:5x 11x 13
273:3x 7x 13
399:3x 7x 19
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 5x 7x 11x 13 = 45045
Therefore, the value for common factors is 45045.
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 = 77103976950/(1x45045)
LCM = 77103976950/45045
LCM = 1711710
Thus, we can understand that the LCM of 990,715,273,399 is 1711710.
