Find LCM of 360,494,390,808 with Prime Factorization
| 2 | 360, 494, 390, 808 |
| 2 | 180, 247, 195, 404 |
| 2 | 90, 247, 195, 202 |
| 3 | 45, 247, 195, 101 |
| 5 | 15, 247, 65, 101 |
| 13 | 3, 247, 13, 101 |
| 3, 19, 1, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 3 x 19 x 1 x 101 = 8980920
Therefore, the lowest common multiple of 360,494,390,808 is 8980920.
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.
360 x 494 x 390 x 808 = 56040940800
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.
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
494 : 1, 2, 13, 19, 26, 38, 247, 494
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
808 : 1, 2, 4, 8, 101, 202, 404, 808
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 360,494,390,808, is 2.
Now, the common factors can be found like this.
360:2x 2x 2x 3x 3x 5
494:2x 13x 19
390:2x 3x 5x 13
808:2x 2x 2x 101
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 5x 13 = 3120
Therefore, the value for common factors is 3120.
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 = 56040940800/(2x3120)
LCM = 56040940800/6240
LCM = 8980920
Thus, we can understand that the LCM of 360,494,390,808 is 8980920.
