Given numbers are 230,642,431,644,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 230,642,431,644,668 is 74396866740.
Find LCM of 230,642,431,644,668 with Prime Factorization
| 2 | 230, 642, 431, 644, 668 |
| 2 | 115, 321, 431, 322, 334 |
| 23 | 115, 321, 431, 161, 167 |
| 5, 321, 431, 7, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 5 x 321 x 431 x 7 x 167 = 74396866740
Therefore, the lowest common multiple of 230,642,431,644,668 is 74396866740.
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.
230 x 642 x 431 x 644 x 668 = 27378046960320
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
642 : 1, 2, 3, 6, 107, 214, 321, 642
431 : 1, 431
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,642,431,644,668, is 1.
Now, the common factors can be found like this.
230:2x 5x 23
642:2x 3x 107
431:431
644:2x 2x 7x 23
668:2x 2x 167
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 2x 23 = 368
Therefore, the value for common factors is 368.
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 = 27378046960320/(1x368)
LCM = 27378046960320/368
LCM = 74396866740
Thus, we can understand that the LCM of 230,642,431,644,668 is 74396866740.
