Given numbers are 860,225,278,800,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,225,278,800,815 is 7014607200.
Find LCM of 860,225,278,800,815 with Prime Factorization
| 2 | 860, 225, 278, 800, 815 |
| 2 | 430, 225, 139, 400, 815 |
| 5 | 215, 225, 139, 200, 815 |
| 5 | 43, 45, 139, 40, 163 |
| 43, 9, 139, 8, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 43 x 9 x 139 x 8 x 163 = 7014607200
Therefore, the lowest common multiple of 860,225,278,800,815 is 7014607200.
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.
860 x 225 x 278 x 800 x 815 = 35073036000000
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
278 : 1, 2, 139, 278
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,225,278,800,815, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
225:3x 3x 5x 5
278:2x 139
800:2x 2x 2x 2x 2x 5x 5
815:5x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 5x 5x 5 = 5000
Therefore, the value for common factors is 5000.
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 = 35073036000000/(1x5000)
LCM = 35073036000000/5000
LCM = 7014607200
Thus, we can understand that the LCM of 860,225,278,800,815 is 7014607200.
