Find LCM of 990,677,704,288 with Prime Factorization
| 2 | 990, 677, 704, 288 |
| 2 | 495, 677, 352, 144 |
| 2 | 495, 677, 176, 72 |
| 2 | 495, 677, 88, 36 |
| 2 | 495, 677, 44, 18 |
| 3 | 495, 677, 22, 9 |
| 3 | 165, 677, 22, 3 |
| 11 | 55, 677, 22, 1 |
| 5, 677, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 11 x 5 x 677 x 2 x 1 = 21447360
Therefore, the lowest common multiple of 990,677,704,288 is 21447360.
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 677 x 704 x 288 = 135890472960
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
677 : 1, 677
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,677,704,288, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
677:677
704:2x 2x 2x 2x 2x 2x 11
288:2x 2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 3x 3x 11 = 6336
Therefore, the value for common factors is 6336.
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 = 135890472960/(1x6336)
LCM = 135890472960/6336
LCM = 21447360
Thus, we can understand that the LCM of 990,677,704,288 is 21447360.
