Given numbers are 837,648,321,81
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 837,648,321,81 is 2149416.
Find LCM of 837,648,321,81 with Prime Factorization
3 | 837, 648, 321, 81 |
3 | 279, 216, 107, 27 |
3 | 93, 72, 107, 9 |
3 | 31, 24, 107, 3 |
31, 8, 107, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 31 x 8 x 107 x 1 = 2149416
Therefore, the lowest common multiple of 837,648,321,81 is 2149416.
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.
837 x 648 x 321 x 81 = 14102318376
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.
837 : 1, 3, 9, 27, 31, 93, 279, 837
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
321 : 1, 3, 107, 321
81 : 1, 3, 9, 27, 81
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,648,321,81, is 3.
Now, the common factors can be found like this.
837:3x 3x 3x 31
648:2x 2x 2x 3x 3x 3x 3
321:3x 107
81:3x 3x 3x 3
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 3x 3x 3x 3x 3 = 2187
Therefore, the value for common factors is 2187.
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 = 14102318376/(3x2187)
LCM = 14102318376/6561
LCM = 2149416
Thus, we can understand that the LCM of 837,648,321,81 is 2149416.
