Find LCM of 828,138,832,450,818 with Prime Factorization
| 2 | 828, 138, 832, 450, 818 |
| 2 | 414, 69, 416, 225, 409 |
| 3 | 207, 69, 208, 225, 409 |
| 3 | 23, 69, 208, 75, 409 |
| 23 | 23, 23, 208, 25, 409 |
| 1, 1, 208, 25, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 1 x 1 x 208 x 25 x 409 = 1760990400
Therefore, the lowest common multiple of 828,138,832,450,818 is 1760990400.
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.
828 x 138 x 832 x 450 x 818 = 34994401228800
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
138 : 1, 2, 3, 6, 23, 46, 69, 138
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
818 : 1, 2, 409, 818
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,138,832,450,818, is 2.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
138:2x 3x 23
832:2x 2x 2x 2x 2x 2x 13
450:2x 3x 3x 5x 5
818:2x 409
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 3x 3x 3x 23 = 9936
Therefore, the value for common factors is 9936.
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 = 34994401228800/(2x9936)
LCM = 34994401228800/19872
LCM = 1760990400
Thus, we can understand that the LCM of 828,138,832,450,818 is 1760990400.
