Given numbers are 235,395,786,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 235,395,786,940 is 29184180.
Find LCM of 235,395,786,940 with Prime Factorization
| 2 | 235, 395, 786, 940 |
| 5 | 235, 395, 393, 470 |
| 47 | 47, 79, 393, 94 |
| 1, 79, 393, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 47 x 1 x 79 x 393 x 2 = 29184180
Therefore, the lowest common multiple of 235,395,786,940 is 29184180.
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.
235 x 395 x 786 x 940 = 68582823000
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.
235 : 1, 5, 47, 235
395 : 1, 5, 79, 395
786 : 1, 2, 3, 6, 131, 262, 393, 786
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 235,395,786,940, is 1.
Now, the common factors can be found like this.
235:5x 47
395:5x 79
786:2x 3x 131
940:2x 2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 47 = 2350
Therefore, the value for common factors is 2350.
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 = 68582823000/(1x2350)
LCM = 68582823000/2350
LCM = 29184180
Thus, we can understand that the LCM of 235,395,786,940 is 29184180.
