Given numbers are 351,731,387,239
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 351,731,387,239 is 61322859.
Find LCM of 351,731,387,239 with Prime Factorization
| 3 | 351, 731, 387, 239 |
| 3 | 117, 731, 129, 239 |
| 43 | 39, 731, 43, 239 |
| 39, 17, 1, 239 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 43 x 39 x 17 x 1 x 239 = 61322859
Therefore, the lowest common multiple of 351,731,387,239 is 61322859.
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.
351 x 731 x 387 x 239 = 23731946433
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
731 : 1, 17, 43, 731
387 : 1, 3, 9, 43, 129, 387
239 : 1, 239
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,731,387,239, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
731:17x 43
387:3x 3x 43
239:239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 43 = 387
Therefore, the value for common factors is 387.
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 = 23731946433/(1x387)
LCM = 23731946433/387
LCM = 61322859
Thus, we can understand that the LCM of 351,731,387,239 is 61322859.
