Given numbers are 839,828,897,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,828,897,249 is 749572668.
Find LCM of 839,828,897,249 with Prime Factorization
| 3 | 839, 828, 897, 249 |
| 23 | 839, 276, 299, 83 |
| 839, 12, 13, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 839 x 12 x 13 x 83 = 749572668
Therefore, the lowest common multiple of 839,828,897,249 is 749572668.
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.
839 x 828 x 897 x 249 = 155161542276
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.
839 : 1, 839
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
897 : 1, 3, 13, 23, 39, 69, 299, 897
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,828,897,249, is 1.
Now, the common factors can be found like this.
839:839
828:2x 2x 3x 3x 23
897:3x 13x 23
249:3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 155161542276/(1x207)
LCM = 155161542276/207
LCM = 749572668
Thus, we can understand that the LCM of 839,828,897,249 is 749572668.
