Given numbers are 321,234,945,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,234,945,105 is 2628990.
Find LCM of 321,234,945,105 with Prime Factorization
3 | 321, 234, 945, 105 |
3 | 107, 78, 315, 35 |
5 | 107, 26, 105, 35 |
7 | 107, 26, 21, 7 |
107, 26, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 107 x 26 x 3 x 1 = 2628990
Therefore, the lowest common multiple of 321,234,945,105 is 2628990.
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.
321 x 234 x 945 x 105 = 7453186650
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.
321 : 1, 3, 107, 321
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
105 : 1, 3, 5, 7, 15, 21, 35, 105
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,234,945,105, is 3.
Now, the common factors can be found like this.
321:3x 107
234:2x 3x 3x 13
945:3x 3x 3x 5x 7
105:3x 5x 7
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 5x 7 = 945
Therefore, the value for common factors is 945.
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 = 7453186650/(3x945)
LCM = 7453186650/2835
LCM = 2628990
Thus, we can understand that the LCM of 321,234,945,105 is 2628990.
