Given numbers are 398,816,687,150,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,816,687,150,817 is 759522742800.
Find LCM of 398,816,687,150,817 with Prime Factorization
| 2 | 398, 816, 687, 150, 817 |
| 3 | 199, 408, 687, 75, 817 |
| 199, 136, 229, 25, 817 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 199 x 136 x 229 x 25 x 817 = 759522742800
Therefore, the lowest common multiple of 398,816,687,150,817 is 759522742800.
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.
398 x 816 x 687 x 150 x 817 = 27342818740800
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.
398 : 1, 2, 199, 398
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
687 : 1, 3, 229, 687
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,816,687,150,817, is 1.
Now, the common factors can be found like this.
398:2x 199
816:2x 2x 2x 2x 3x 17
687:3x 229
150:2x 3x 5x 5
817:19x 43
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 27342818740800/(1x36)
LCM = 27342818740800/36
LCM = 759522742800
Thus, we can understand that the LCM of 398,816,687,150,817 is 759522742800.
