The LCM of 808,654,660,900 is 217978200.
Find LCM of 808,654,660,900 with Prime Factorization
2 | 808, 654, 660, 900 |
2 | 404, 327, 330, 450 |
3 | 202, 327, 165, 225 |
5 | 202, 109, 55, 75 |
202, 109, 11, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 202 x 109 x 11 x 15 = 217978200
Therefore, the lowest common multiple of 808,654,660,900 is 217978200.
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 654 x 660 x 900 = 313888608000
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
654 : 1, 2, 3, 6, 109, 218, 327, 654
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,654,660,900, is 2.
Now, the common factors can be found like this.
808:2x 2x 2x 101
654:2x 3x 109
660:2x 2x 3x 5x 11
900:2x 2x 3x 3x 5x 5
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 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 313888608000/(2x720)
LCM = 313888608000/1440
LCM = 217978200
Thus, we can understand that the LCM of 808,654,660,900 is 217978200.
