Given numbers are 931,687,774,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,687,774,387 is 165016026.
Find LCM of 931,687,774,387 with Prime Factorization
| 3 | 931, 687, 774, 387 |
| 3 | 931, 229, 258, 129 |
| 43 | 931, 229, 86, 43 |
| 931, 229, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 43 x 931 x 229 x 2 x 1 = 165016026
Therefore, the lowest common multiple of 931,687,774,387 is 165016026.
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.
931 x 687 x 774 x 387 = 191583606186
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.
931 : 1, 7, 19, 49, 133, 931
687 : 1, 3, 229, 687
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,687,774,387, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
687:3x 229
774:2x 3x 3x 43
387:3x 3x 43
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 3x 43 = 1161
Therefore, the value for common factors is 1161.
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 = 191583606186/(1x1161)
LCM = 191583606186/1161
LCM = 165016026
Thus, we can understand that the LCM of 931,687,774,387 is 165016026.
