Given numbers are 815,600,380,487
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,600,380,487 is 904943400.
Find LCM of 815,600,380,487 with Prime Factorization
| 2 | 815, 600, 380, 487 |
| 2 | 815, 300, 190, 487 |
| 5 | 815, 150, 95, 487 |
| 163, 30, 19, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 163 x 30 x 19 x 487 = 904943400
Therefore, the lowest common multiple of 815,600,380,487 is 904943400.
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.
815 x 600 x 380 x 487 = 90494340000
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.
815 : 1, 5, 163, 815
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
487 : 1, 487
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,600,380,487, is 1.
Now, the common factors can be found like this.
815:5x 163
600:2x 2x 2x 3x 5x 5
380:2x 2x 5x 19
487:487
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 90494340000/(1x100)
LCM = 90494340000/100
LCM = 904943400
Thus, we can understand that the LCM of 815,600,380,487 is 904943400.
