Given numbers are 187,987,667,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,987,667,805 is 615537615.
Find LCM of 187,987,667,805 with Prime Factorization
| 7 | 187, 987, 667, 805 |
| 23 | 187, 141, 667, 115 |
| 187, 141, 29, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 187 x 141 x 29 x 5 = 615537615
Therefore, the lowest common multiple of 187,987,667,805 is 615537615.
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 987 x 667 x 805 = 99101556015
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
987 : 1, 3, 7, 21, 47, 141, 329, 987
667 : 1, 23, 29, 667
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,987,667,805, is 1.
Now, the common factors can be found like this.
187:11x 17
987:3x 7x 47
667:23x 29
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 99101556015/(1x161)
LCM = 99101556015/161
LCM = 615537615
Thus, we can understand that the LCM of 187,987,667,805 is 615537615.
