Given numbers are 855,993,100,731,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,993,100,731,678 is 467541240300.
Find LCM of 855,993,100,731,678 with Prime Factorization
| 2 | 855, 993, 100, 731, 678 |
| 3 | 855, 993, 50, 731, 339 |
| 5 | 285, 331, 50, 731, 113 |
| 57, 331, 10, 731, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 57 x 331 x 10 x 731 x 113 = 467541240300
Therefore, the lowest common multiple of 855,993,100,731,678 is 467541240300.
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.
855 x 993 x 100 x 731 x 678 = 42078711627000
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
993 : 1, 3, 331, 993
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
731 : 1, 17, 43, 731
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,993,100,731,678, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
993:3x 331
100:2x 2x 5x 5
731:17x 43
678:2x 3x 113
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 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 42078711627000/(1x90)
LCM = 42078711627000/90
LCM = 467541240300
Thus, we can understand that the LCM of 855,993,100,731,678 is 467541240300.
