Given numbers are 808,656,742,576
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,656,742,576 is 884915136.
Find LCM of 808,656,742,576 with Prime Factorization
| 2 | 808, 656, 742, 576 |
| 2 | 404, 328, 371, 288 |
| 2 | 202, 164, 371, 144 |
| 2 | 101, 82, 371, 72 |
| 101, 41, 371, 36 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 101 x 41 x 371 x 36 = 884915136
Therefore, the lowest common multiple of 808,656,742,576 is 884915136.
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.
808 x 656 x 742 x 576 = 226538274816
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
742 : 1, 2, 7, 14, 53, 106, 371, 742
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,656,742,576, is 2.
Now, the common factors can be found like this.
808:2x 2x 2x 101
656:2x 2x 2x 2x 41
742:2x 7x 53
576:2x 2x 2x 2x 2x 2x 3x 3
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 2 = 128
Therefore, the value for common factors is 128.
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 = 226538274816/(2x128)
LCM = 226538274816/256
LCM = 884915136
Thus, we can understand that the LCM of 808,656,742,576 is 884915136.
