Given numbers are 403,789,676,195,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,789,676,195,908 is 18766412340.
Find LCM of 403,789,676,195,908 with Prime Factorization
| 2 | 403, 789, 676, 195, 908 |
| 2 | 403, 789, 338, 195, 454 |
| 3 | 403, 789, 169, 195, 227 |
| 13 | 403, 263, 169, 65, 227 |
| 31, 263, 13, 5, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 31 x 263 x 13 x 5 x 227 = 18766412340
Therefore, the lowest common multiple of 403,789,676,195,908 is 18766412340.
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 789 x 676 x 195 x 908 = 38058284225520
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
789 : 1, 3, 263, 789
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
195 : 1, 3, 5, 13, 15, 39, 65, 195
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,789,676,195,908, is 1.
Now, the common factors can be found like this.
403:13x 31
789:3x 263
676:2x 2x 13x 13
195:3x 5x 13
908:2x 2x 227
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 13x 13 = 2028
Therefore, the value for common factors is 2028.
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 = 38058284225520/(1x2028)
LCM = 38058284225520/2028
LCM = 18766412340
Thus, we can understand that the LCM of 403,789,676,195,908 is 18766412340.
