Find LCM of 822,323,357,782,642 with Prime Factorization
| 2 | 822, 323, 357, 782, 642 |
| 3 | 411, 323, 357, 391, 321 |
| 17 | 137, 323, 119, 391, 107 |
| 137, 19, 7, 23, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 137 x 19 x 7 x 23 x 107 = 4573871862
Therefore, the lowest common multiple of 822,323,357,782,642 is 4573871862.
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.
822 x 323 x 357 x 782 x 642 = 47586562852248
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
323 : 1, 17, 19, 323
357 : 1, 3, 7, 17, 21, 51, 119, 357
782 : 1, 2, 17, 23, 34, 46, 391, 782
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 822,323,357,782,642, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
323:17x 19
357:3x 7x 17
782:2x 17x 23
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 2x 3x 3x 17x 17 = 10404
Therefore, the value for common factors is 10404.
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 = 47586562852248/(1x10404)
LCM = 47586562852248/10404
LCM = 4573871862
Thus, we can understand that the LCM of 822,323,357,782,642 is 4573871862.
