Given numbers are 364,391,655,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 364,391,655,731 is 4008555460.
Find LCM of 364,391,655,731 with Prime Factorization
| 17 | 364, 391, 655, 731 |
| 364, 23, 655, 43 |
Multiply the prime numbers at the bottom and the left side.
17 x 364 x 23 x 655 x 43 = 4008555460
Therefore, the lowest common multiple of 364,391,655,731 is 4008555460.
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.
364 x 391 x 655 x 731 = 68145442820
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.
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
391 : 1, 17, 23, 391
655 : 1, 5, 131, 655
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,391,655,731, is 1.
Now, the common factors can be found like this.
364:2x 2x 7x 13
391:17x 23
655:5x 131
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.
17 = 17
Therefore, the value for common factors is 17.
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 = 68145442820/(1x17)
LCM = 68145442820/17
LCM = 4008555460
Thus, we can understand that the LCM of 364,391,655,731 is 4008555460.
