Given numbers are 998,999,105,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,999,105,851 is 802586610.
Find LCM of 998,999,105,851 with Prime Factorization
| 3 | 998, 999, 105, 851 |
| 37 | 998, 333, 35, 851 |
| 998, 9, 35, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 37 x 998 x 9 x 35 x 23 = 802586610
Therefore, the lowest common multiple of 998,999,105,851 is 802586610.
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.
998 x 999 x 105 x 851 = 89087113710
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.
998 : 1, 2, 499, 998
999 : 1, 3, 9, 27, 37, 111, 333, 999
105 : 1, 3, 5, 7, 15, 21, 35, 105
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,999,105,851, is 1.
Now, the common factors can be found like this.
998:2x 499
999:3x 3x 3x 37
105:3x 5x 7
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 37 = 111
Therefore, the value for common factors is 111.
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 = 89087113710/(1x111)
LCM = 89087113710/111
LCM = 802586610
Thus, we can understand that the LCM of 998,999,105,851 is 802586610.
