The LCM of 403,826,552,621 is 826868952.
Find LCM of 403,826,552,621 with Prime Factorization
| 2 | 403, 826, 552, 621 |
| 3 | 403, 413, 276, 621 |
| 23 | 403, 413, 92, 207 |
| 403, 413, 4, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 403 x 413 x 4 x 9 = 826868952
Therefore, the lowest common multiple of 403,826,552,621 is 826868952.
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.
403 x 826 x 552 x 621 = 114107915376
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.
403 : 1, 13, 31, 403
826 : 1, 2, 7, 14, 59, 118, 413, 826
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,826,552,621, is 1.
Now, the common factors can be found like this.
403:13x 31
826:2x 7x 59
552:2x 2x 2x 3x 23
621:3x 3x 3x 23
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 23 = 138
Therefore, the value for common factors is 138.
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 = 114107915376/(1x138)
LCM = 114107915376/138
LCM = 826868952
Thus, we can understand that the LCM of 403,826,552,621 is 826868952.
