Given numbers are 247,815,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,815,494 is 402610.
Find LCM of 247,815,494 with Prime Factorization
| 13 | 247, 815, 494 |
| 19 | 19, 815, 38 |
| 1, 815, 2 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 1 x 815 x 2 = 402610
Therefore, the lowest common multiple of 247,815,494 is 402610.
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.
247 x 815 x 494 = 99444670
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.
247 : 1, 13, 19, 247
815 : 1, 5, 163, 815
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,815,494, is 1.
Now, the common factors can be found like this.
247:13x 19
815:5x 163
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 99444670/(1x247)
LCM = 99444670/247
LCM = 402610
Thus, we can understand that the LCM of 247,815,494 is 402610.
