The LCM of 494,646,862,774,399 is 9805328442.
Find LCM of 494,646,862,774,399 with Prime Factorization
| 2 | 494, 646, 862, 774, 399 |
| 3 | 247, 323, 431, 387, 399 |
| 19 | 247, 323, 431, 129, 133 |
| 13, 17, 431, 129, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 13 x 17 x 431 x 129 x 7 = 9805328442
Therefore, the lowest common multiple of 494,646,862,774,399 is 9805328442.
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.
494 x 646 x 862 x 774 x 399 = 84953365621488
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
646 : 1, 2, 17, 19, 34, 38, 323, 646
862 : 1, 2, 431, 862
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,646,862,774,399, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
646:2x 17x 19
862:2x 431
774:2x 3x 3x 43
399:3x 7x 19
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 3x 19x 19 = 8664
Therefore, the value for common factors is 8664.
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 = 84953365621488/(1x8664)
LCM = 84953365621488/8664
LCM = 9805328442
Thus, we can understand that the LCM of 494,646,862,774,399 is 9805328442.
