The LCM of 123,400,631,686,105 is 10648503600.
Find LCM of 123,400,631,686,105 with Prime Factorization
2 | 123, 400, 631, 686, 105 |
3 | 123, 200, 631, 343, 105 |
5 | 41, 200, 631, 343, 35 |
7 | 41, 40, 631, 343, 7 |
41, 40, 631, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 41 x 40 x 631 x 49 x 1 = 10648503600
Therefore, the lowest common multiple of 123,400,631,686,105 is 10648503600.
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.
123 x 400 x 631 x 686 x 105 = 2236185756000
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.
123 : 1, 3, 41, 123
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
631 : 1, 631
686 : 1, 2, 7, 14, 49, 98, 343, 686
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,400,631,686,105, is 1.
Now, the common factors can be found like this.
123:3x 41
400:2x 2x 2x 2x 5x 5
631:631
686:2x 7x 7x 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.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 2236185756000/(1x210)
LCM = 2236185756000/210
LCM = 10648503600
Thus, we can understand that the LCM of 123,400,631,686,105 is 10648503600.
