Given numbers are 187,793,897,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,793,897,989 is 439979397.
Find LCM of 187,793,897,989 with Prime Factorization
| 13 | 187, 793, 897, 989 |
| 23 | 187, 61, 69, 989 |
| 187, 61, 3, 43 |
Multiply the prime numbers at the bottom and the left side.
13 x 23 x 187 x 61 x 3 x 43 = 439979397
Therefore, the lowest common multiple of 187,793,897,989 is 439979397.
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.
187 x 793 x 897 x 989 = 131553839703
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.
187 : 1, 11, 17, 187
793 : 1, 13, 61, 793
897 : 1, 3, 13, 23, 39, 69, 299, 897
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,793,897,989, is 1.
Now, the common factors can be found like this.
187:11x 17
793:13x 61
897:3x 13x 23
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 23 = 299
Therefore, the value for common factors is 299.
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 = 131553839703/(1x299)
LCM = 131553839703/299
LCM = 439979397
Thus, we can understand that the LCM of 187,793,897,989 is 439979397.
