Given numbers are 802,857,905,180,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,857,905,180,819 is 1018867400460.
Find LCM of 802,857,905,180,819 with Prime Factorization
| 2 | 802, 857, 905, 180, 819 |
| 3 | 401, 857, 905, 90, 819 |
| 3 | 401, 857, 905, 30, 273 |
| 5 | 401, 857, 905, 10, 91 |
| 401, 857, 181, 2, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 401 x 857 x 181 x 2 x 91 = 1018867400460
Therefore, the lowest common multiple of 802,857,905,180,819 is 1018867400460.
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.
802 x 857 x 905 x 180 x 819 = 91698066041400
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.
802 : 1, 2, 401, 802
857 : 1, 857
905 : 1, 5, 181, 905
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,857,905,180,819, is 1.
Now, the common factors can be found like this.
802:2x 401
857:857
905:5x 181
180:2x 2x 3x 3x 5
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 91698066041400/(1x90)
LCM = 91698066041400/90
LCM = 1018867400460
Thus, we can understand that the LCM of 802,857,905,180,819 is 1018867400460.
