Given numbers are 867,731,774,712
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,731,774,712 is 79632216.
Find LCM of 867,731,774,712 with Prime Factorization
| 2 | 867, 731, 774, 712 |
| 3 | 867, 731, 387, 356 |
| 17 | 289, 731, 129, 356 |
| 43 | 17, 43, 129, 356 |
| 17, 1, 3, 356 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 43 x 17 x 1 x 3 x 356 = 79632216
Therefore, the lowest common multiple of 867,731,774,712 is 79632216.
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.
867 x 731 x 774 x 712 = 349266899376
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.
867 : 1, 3, 17, 51, 289, 867
731 : 1, 17, 43, 731
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
712 : 1, 2, 4, 8, 89, 178, 356, 712
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,731,774,712, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
731:17x 43
774:2x 3x 3x 43
712:2x 2x 2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17x 43 = 4386
Therefore, the value for common factors is 4386.
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 = 349266899376/(1x4386)
LCM = 349266899376/4386
LCM = 79632216
Thus, we can understand that the LCM of 867,731,774,712 is 79632216.
