Find LCM of 682,416,842,396,858 with Prime Factorization
| 2 | 682, 416, 842, 396, 858 |
| 2 | 341, 208, 421, 198, 429 |
| 3 | 341, 104, 421, 99, 429 |
| 11 | 341, 104, 421, 33, 143 |
| 13 | 31, 104, 421, 3, 13 |
| 31, 8, 421, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 31 x 8 x 421 x 3 x 1 = 537492384
Therefore, the lowest common multiple of 682,416,842,396,858 is 537492384.
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.
682 x 416 x 842 x 396 x 858 = 81165649923072
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
842 : 1, 2, 421, 842
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,416,842,396,858, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
416:2x 2x 2x 2x 2x 13
842:2x 421
396:2x 2x 3x 3x 11
858:2x 3x 11x 13
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 3x 11x 11x 13 = 75504
Therefore, the value for common factors is 75504.
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 = 81165649923072/(2x75504)
LCM = 81165649923072/151008
LCM = 537492384
Thus, we can understand that the LCM of 682,416,842,396,858 is 537492384.
