Given numbers are 324,278,836,220,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 324,278,836,220,494 is 611814060.
Find LCM of 324,278,836,220,494 with Prime Factorization
| 2 | 324, 278, 836, 220, 494 |
| 2 | 162, 139, 418, 110, 247 |
| 11 | 81, 139, 209, 55, 247 |
| 19 | 81, 139, 19, 5, 247 |
| 81, 139, 1, 5, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 81 x 139 x 1 x 5 x 13 = 611814060
Therefore, the lowest common multiple of 324,278,836,220,494 is 611814060.
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.
324 x 278 x 836 x 220 x 494 = 8183624866560
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.
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
278 : 1, 2, 139, 278
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
494 : 1, 2, 13, 19, 26, 38, 247, 494
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 324,278,836,220,494, is 2.
Now, the common factors can be found like this.
324:2x 2x 3x 3x 3x 3
278:2x 139
836:2x 2x 11x 19
220:2x 2x 5x 11
494:2x 13x 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 2x 2x 11x 19 = 6688
Therefore, the value for common factors is 6688.
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 = 8183624866560/(2x6688)
LCM = 8183624866560/13376
LCM = 611814060
Thus, we can understand that the LCM of 324,278,836,220,494 is 611814060.
