Given numbers are 403,172,731,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,172,731,871 is 78950924.
Find LCM of 403,172,731,871 with Prime Factorization
| 13 | 403, 172, 731, 871 |
| 43 | 31, 172, 731, 67 |
| 31, 4, 17, 67 |
Multiply the prime numbers at the bottom and the left side.
13 x 43 x 31 x 4 x 17 x 67 = 78950924
Therefore, the lowest common multiple of 403,172,731,871 is 78950924.
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.
403 x 172 x 731 x 871 = 44133566516
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.
403 : 1, 13, 31, 403
172 : 1, 2, 4, 43, 86, 172
731 : 1, 17, 43, 731
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,172,731,871, is 1.
Now, the common factors can be found like this.
403:13x 31
172:2x 2x 43
731:17x 43
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 43 = 559
Therefore, the value for common factors is 559.
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 = 44133566516/(1x559)
LCM = 44133566516/559
LCM = 78950924
Thus, we can understand that the LCM of 403,172,731,871 is 78950924.
