Given numbers are 999,343,239,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 999,343,239,686 is 163790046.
Find LCM of 999,343,239,686 with Prime Factorization
7 | 999, 343, 239, 686 |
7 | 999, 49, 239, 98 |
7 | 999, 7, 239, 14 |
999, 1, 239, 2 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 7 x 999 x 1 x 239 x 2 = 163790046
Therefore, the lowest common multiple of 999,343,239,686 is 163790046.
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.
999 x 343 x 239 x 686 = 56179985778
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.
999 : 1, 3, 9, 27, 37, 111, 333, 999
343 : 1, 7, 49, 343
239 : 1, 239
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 999,343,239,686, is 1.
Now, the common factors can be found like this.
999:3x 3x 3x 37
343:7x 7x 7
239:239
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 7 = 343
Therefore, the value for common factors is 343.
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 = 56179985778/(1x343)
LCM = 56179985778/343
LCM = 163790046
Thus, we can understand that the LCM of 999,343,239,686 is 163790046.
