Given numbers are 828,621,731,713
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 828,621,731,713 is 56289924.
Find LCM of 828,621,731,713 with Prime Factorization
| 3 | 828, 621, 731, 713 |
| 3 | 276, 207, 731, 713 |
| 23 | 92, 69, 731, 713 |
| 4, 3, 731, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 4 x 3 x 731 x 31 = 56289924
Therefore, the lowest common multiple of 828,621,731,713 is 56289924.
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.
828 x 621 x 731 x 713 = 267996328164
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
621 : 1, 3, 9, 23, 27, 69, 207, 621
731 : 1, 17, 43, 731
713 : 1, 23, 31, 713
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,621,731,713, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
621:3x 3x 3x 23
731:17x 43
713:23x 31
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 23x 23 = 4761
Therefore, the value for common factors is 4761.
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 = 267996328164/(1x4761)
LCM = 267996328164/4761
LCM = 56289924
Thus, we can understand that the LCM of 828,621,731,713 is 56289924.
