Given numbers are 805,990,546,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,990,546,164 is 169909740.
Find LCM of 805,990,546,164 with Prime Factorization
| 2 | 805, 990, 546, 164 |
| 3 | 805, 495, 273, 82 |
| 5 | 805, 165, 91, 82 |
| 7 | 161, 33, 91, 82 |
| 23, 33, 13, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 33 x 13 x 82 = 169909740
Therefore, the lowest common multiple of 805,990,546,164 is 169909740.
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.
805 x 990 x 546 x 164 = 71362090800
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,990,546,164, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
990:2x 3x 3x 5x 11
546:2x 3x 7x 13
164:2x 2x 41
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 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 71362090800/(1x420)
LCM = 71362090800/420
LCM = 169909740
Thus, we can understand that the LCM of 805,990,546,164 is 169909740.
