Find LCM of 990,309,917,469,814 with Prime Factorization
| 2 | 990, 309, 917, 469, 814 |
| 3 | 495, 309, 917, 469, 407 |
| 7 | 165, 103, 917, 469, 407 |
| 11 | 165, 103, 131, 67, 407 |
| 15, 103, 131, 67, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 15 x 103 x 131 x 67 x 37 = 231802588710
Therefore, the lowest common multiple of 990,309,917,469,814 is 231802588710.
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 309 x 917 x 469 x 814 = 107092795984020
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
309 : 1, 3, 103, 309
917 : 1, 7, 131, 917
469 : 1, 7, 67, 469
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,309,917,469,814, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
309:3x 103
917:7x 131
469:7x 67
814:2x 11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 107092795984020/(1x462)
LCM = 107092795984020/462
LCM = 231802588710
Thus, we can understand that the LCM of 990,309,917,469,814 is 231802588710.
