The LCM of 321,940,130,936 is 23535720.
Find LCM of 321,940,130,936 with Prime Factorization
| 2 | 321, 940, 130, 936 |
| 2 | 321, 470, 65, 468 |
| 3 | 321, 235, 65, 234 |
| 5 | 107, 235, 65, 78 |
| 13 | 107, 47, 13, 78 |
| 107, 47, 1, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 107 x 47 x 1 x 6 = 23535720
Therefore, the lowest common multiple of 321,940,130,936 is 23535720.
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 940 x 130 x 936 = 36715723200
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
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
130 : 1, 2, 5, 10, 13, 26, 65, 130
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,940,130,936, is 1.
Now, the common factors can be found like this.
321:3x 107
940:2x 2x 5x 47
130:2x 5x 13
936:2x 2x 2x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 36715723200/(1x1560)
LCM = 36715723200/1560
LCM = 23535720
Thus, we can understand that the LCM of 321,940,130,936 is 23535720.
