Given numbers are 866,900,989,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,900,989,391 is 6552026100.
Find LCM of 866,900,989,391 with Prime Factorization
| 2 | 866, 900, 989, 391 |
| 23 | 433, 450, 989, 391 |
| 433, 450, 43, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 433 x 450 x 43 x 17 = 6552026100
Therefore, the lowest common multiple of 866,900,989,391 is 6552026100.
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.
866 x 900 x 989 x 391 = 301393200600
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.
866 : 1, 2, 433, 866
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
989 : 1, 23, 43, 989
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,900,989,391, is 1.
Now, the common factors can be found like this.
866:2x 433
900:2x 2x 3x 3x 5x 5
989:23x 43
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23 = 46
Therefore, the value for common factors is 46.
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 = 301393200600/(1x46)
LCM = 301393200600/46
LCM = 6552026100
Thus, we can understand that the LCM of 866,900,989,391 is 6552026100.
