Given numbers are 860,731,958,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,731,958,940 is 329140060.
Find LCM of 860,731,958,940 with Prime Factorization
| 2 | 860, 731, 958, 940 |
| 2 | 430, 731, 479, 470 |
| 5 | 215, 731, 479, 235 |
| 43 | 43, 731, 479, 47 |
| 1, 17, 479, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 1 x 17 x 479 x 47 = 329140060
Therefore, the lowest common multiple of 860,731,958,940 is 329140060.
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.
860 x 731 x 958 x 940 = 566120903200
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
731 : 1, 17, 43, 731
958 : 1, 2, 479, 958
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 860,731,958,940, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
731:17x 43
958:2x 479
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 2x 2x 5x 43 = 1720
Therefore, the value for common factors is 1720.
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 = 566120903200/(1x1720)
LCM = 566120903200/1720
LCM = 329140060
Thus, we can understand that the LCM of 860,731,958,940 is 329140060.
