Find LCM of 828,414,369,642,321 with Prime Factorization
| 2 | 828, 414, 369, 642, 321 |
| 3 | 414, 207, 369, 321, 321 |
| 3 | 138, 69, 123, 107, 107 |
| 23 | 46, 23, 41, 107, 107 |
| 107 | 2, 1, 41, 107, 107 |
| 2, 1, 41, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 23 x 107 x 2 x 1 x 41 x 1 x 1 = 3632436
Therefore, the lowest common multiple of 828,414,369,642,321 is 3632436.
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.
828 x 414 x 369 x 642 x 321 = 26067363288336
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
369 : 1, 3, 9, 41, 123, 369
642 : 1, 2, 3, 6, 107, 214, 321, 642
321 : 1, 3, 107, 321
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,414,369,642,321, is 3.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
414:2x 3x 3x 23
369:3x 3x 41
642:2x 3x 107
321:3x 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 2x 3x 3x 3x 3x 3x 23x 107 = 2392092
Therefore, the value for common factors is 2392092.
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 = 26067363288336/(3x2392092)
LCM = 26067363288336/7176276
LCM = 3632436
Thus, we can understand that the LCM of 828,414,369,642,321 is 3632436.
