Find LCM of 494,551,832,240,978 with Prime Factorization
| 2 | 494, 551, 832, 240, 978 |
| 2 | 247, 551, 416, 120, 489 |
| 2 | 247, 551, 208, 60, 489 |
| 2 | 247, 551, 104, 30, 489 |
| 3 | 247, 551, 52, 15, 489 |
| 13 | 247, 551, 52, 5, 163 |
| 19 | 19, 551, 4, 5, 163 |
| 1, 29, 4, 5, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 19 x 1 x 29 x 4 x 5 x 163 = 1120866240
Therefore, the lowest common multiple of 494,551,832,240,978 is 1120866240.
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 551 x 832 x 240 x 978 = 53155960565760
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
551 : 1, 19, 29, 551
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,551,832,240,978, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
551:19x 29
832:2x 2x 2x 2x 2x 2x 13
240:2x 2x 2x 2x 3x 5
978:2x 3x 163
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 2x 3x 13x 19 = 47424
Therefore, the value for common factors is 47424.
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 = 53155960565760/(1x47424)
LCM = 53155960565760/47424
LCM = 1120866240
Thus, we can understand that the LCM of 494,551,832,240,978 is 1120866240.
