Given numbers are 348,871,676,970,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 348,871,676,970,731 is 1397011132140.
Find LCM of 348,871,676,970,731 with Prime Factorization
| 2 | 348, 871, 676, 970, 731 |
| 2 | 174, 871, 338, 485, 731 |
| 13 | 87, 871, 169, 485, 731 |
| 87, 67, 13, 485, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 87 x 67 x 13 x 485 x 731 = 1397011132140
Therefore, the lowest common multiple of 348,871,676,970,731 is 1397011132140.
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.
348 x 871 x 676 x 970 x 731 = 145289157742560
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.
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
871 : 1, 13, 67, 871
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
970 : 1, 2, 5, 10, 97, 194, 485, 970
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 348,871,676,970,731, is 1.
Now, the common factors can be found like this.
348:2x 2x 3x 29
871:13x 67
676:2x 2x 13x 13
970:2x 5x 97
731:17x 43
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 13 = 104
Therefore, the value for common factors is 104.
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 = 145289157742560/(1x104)
LCM = 145289157742560/104
LCM = 1397011132140
Thus, we can understand that the LCM of 348,871,676,970,731 is 1397011132140.
