Given numbers are 399,856,735,727
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,856,735,727 is 8690587080.
Find LCM of 399,856,735,727 with Prime Factorization
| 3 | 399, 856, 735, 727 |
| 7 | 133, 856, 245, 727 |
| 19, 856, 35, 727 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 856 x 35 x 727 = 8690587080
Therefore, the lowest common multiple of 399,856,735,727 is 8690587080.
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.
399 x 856 x 735 x 727 = 182502328680
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
856 : 1, 2, 4, 8, 107, 214, 428, 856
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
727 : 1, 727
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,856,735,727, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
856:2x 2x 2x 107
735:3x 5x 7x 7
727:727
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 182502328680/(1x21)
LCM = 182502328680/21
LCM = 8690587080
Thus, we can understand that the LCM of 399,856,735,727 is 8690587080.
