The LCM of 615,998,120,925,755 is 68582659800.
Find LCM of 615,998,120,925,755 with Prime Factorization
| 2 | 615, 998, 120, 925, 755 |
| 3 | 615, 499, 60, 925, 755 |
| 5 | 205, 499, 20, 925, 755 |
| 41, 499, 4, 185, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 499 x 4 x 185 x 151 = 68582659800
Therefore, the lowest common multiple of 615,998,120,925,755 is 68582659800.
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.
615 x 998 x 120 x 925 x 755 = 51436994850000
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
998 : 1, 2, 499, 998
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
925 : 1, 5, 25, 37, 185, 925
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,998,120,925,755, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
998:2x 499
120:2x 2x 2x 3x 5
925:5x 5x 37
755:5x 151
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 5x 5x 5 = 750
Therefore, the value for common factors is 750.
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 = 51436994850000/(1x750)
LCM = 51436994850000/750
LCM = 68582659800
Thus, we can understand that the LCM of 615,998,120,925,755 is 68582659800.
