Given numbers are 270,168,731,973,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 270,168,731,973,442 is 9986132520.
Find LCM of 270,168,731,973,442 with Prime Factorization
| 2 | 270, 168, 731, 973, 442 |
| 3 | 135, 84, 731, 973, 221 |
| 7 | 45, 28, 731, 973, 221 |
| 17 | 45, 4, 731, 139, 221 |
| 45, 4, 43, 139, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 45 x 4 x 43 x 139 x 13 = 9986132520
Therefore, the lowest common multiple of 270,168,731,973,442 is 9986132520.
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.
270 x 168 x 731 x 973 x 442 = 14260197238560
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.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
731 : 1, 17, 43, 731
973 : 1, 7, 139, 973
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,168,731,973,442, is 1.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
168:2x 2x 2x 3x 7
731:17x 43
973:7x 139
442:2x 13x 17
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 3x 7x 17 = 1428
Therefore, the value for common factors is 1428.
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 = 14260197238560/(1x1428)
LCM = 14260197238560/1428
LCM = 9986132520
Thus, we can understand that the LCM of 270,168,731,973,442 is 9986132520.
