Given numbers are 189,681,403,682,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,681,403,682,808 is 153672711192.
Find LCM of 189,681,403,682,808 with Prime Factorization
| 2 | 189, 681, 403, 682, 808 |
| 3 | 189, 681, 403, 341, 404 |
| 31 | 63, 227, 403, 341, 404 |
| 63, 227, 13, 11, 404 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 63 x 227 x 13 x 11 x 404 = 153672711192
Therefore, the lowest common multiple of 189,681,403,682,808 is 153672711192.
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.
189 x 681 x 403 x 682 x 808 = 28583124281712
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
681 : 1, 3, 227, 681
403 : 1, 13, 31, 403
682 : 1, 2, 11, 22, 31, 62, 341, 682
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,681,403,682,808, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
681:3x 227
403:13x 31
682:2x 11x 31
808:2x 2x 2x 101
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 31 = 186
Therefore, the value for common factors is 186.
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 = 28583124281712/(1x186)
LCM = 28583124281712/186
LCM = 153672711192
Thus, we can understand that the LCM of 189,681,403,682,808 is 153672711192.
