Given numbers are 715,731,170,614
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,731,170,614 is 320916310.
Find LCM of 715,731,170,614 with Prime Factorization
| 2 | 715, 731, 170, 614 |
| 5 | 715, 731, 85, 307 |
| 17 | 143, 731, 17, 307 |
| 143, 43, 1, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 143 x 43 x 1 x 307 = 320916310
Therefore, the lowest common multiple of 715,731,170,614 is 320916310.
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.
715 x 731 x 170 x 614 = 54555772700
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
731 : 1, 17, 43, 731
170 : 1, 2, 5, 10, 17, 34, 85, 170
614 : 1, 2, 307, 614
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,731,170,614, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
731:17x 43
170:2x 5x 17
614:2x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 54555772700/(1x170)
LCM = 54555772700/170
LCM = 320916310
Thus, we can understand that the LCM of 715,731,170,614 is 320916310.
