Find LCM of 897,408,403,820,983 with Prime Factorization
| 2 | 897, 408, 403, 820, 983 |
| 2 | 897, 204, 403, 410, 983 |
| 3 | 897, 102, 403, 205, 983 |
| 13 | 299, 34, 403, 205, 983 |
| 23, 34, 31, 205, 983 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 23 x 34 x 31 x 205 x 983 = 762079754280
Therefore, the lowest common multiple of 897,408,403,820,983 is 762079754280.
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.
897 x 408 x 403 x 820 x 983 = 118884441667680
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
403 : 1, 13, 31, 403
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
983 : 1, 983
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,408,403,820,983, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
408:2x 2x 2x 3x 17
403:13x 31
820:2x 2x 5x 41
983:983
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 118884441667680/(1x156)
LCM = 118884441667680/156
LCM = 762079754280
Thus, we can understand that the LCM of 897,408,403,820,983 is 762079754280.
