Given numbers are 469,670,642,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 469,670,642,842 is 633811290.
Find LCM of 469,670,642,842 with Prime Factorization
| 2 | 469, 670, 642, 842 |
| 67 | 469, 335, 321, 421 |
| 7, 5, 321, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 67 x 7 x 5 x 321 x 421 = 633811290
Therefore, the lowest common multiple of 469,670,642,842 is 633811290.
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.
469 x 670 x 642 x 842 = 169861425720
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.
469 : 1, 7, 67, 469
670 : 1, 2, 5, 10, 67, 134, 335, 670
642 : 1, 2, 3, 6, 107, 214, 321, 642
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,670,642,842, is 1.
Now, the common factors can be found like this.
469:7x 67
670:2x 5x 67
642:2x 3x 107
842:2x 421
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 67 = 268
Therefore, the value for common factors is 268.
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 = 169861425720/(1x268)
LCM = 169861425720/268
LCM = 633811290
Thus, we can understand that the LCM of 469,670,642,842 is 633811290.
