Given numbers are 494,559,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 494,559,642 is 6818682.
Find LCM of 494,559,642 with Prime Factorization
| 2 | 494, 559, 642 |
| 13 | 247, 559, 321 |
| 19, 43, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 43 x 321 = 6818682
Therefore, the lowest common multiple of 494,559,642 is 6818682.
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.
494 x 559 x 642 = 177285732
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
559 : 1, 13, 43, 559
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,559,642, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
559:13x 43
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 177285732/(1x26)
LCM = 177285732/26
LCM = 6818682
Thus, we can understand that the LCM of 494,559,642 is 6818682.
