The LCM of 403,920,991,900,488 is 1008576574200.
Find LCM of 403,920,991,900,488 with Prime Factorization
| 2 | 403, 920, 991, 900, 488 |
| 2 | 403, 460, 991, 450, 244 |
| 2 | 403, 230, 991, 225, 122 |
| 5 | 403, 115, 991, 225, 61 |
| 403, 23, 991, 45, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 403 x 23 x 991 x 45 x 61 = 1008576574200
Therefore, the lowest common multiple of 403,920,991,900,488 is 1008576574200.
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 920 x 991 x 900 x 488 = 161372251872000
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
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
991 : 1, 991
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,920,991,900,488, is 1.
Now, the common factors can be found like this.
403:13x 31
920:2x 2x 2x 5x 23
991:991
900:2x 2x 3x 3x 5x 5
488:2x 2x 2x 61
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 5 = 160
Therefore, the value for common factors is 160.
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 = 161372251872000/(1x160)
LCM = 161372251872000/160
LCM = 1008576574200
Thus, we can understand that the LCM of 403,920,991,900,488 is 1008576574200.
