Given numbers are 772,438,613,687,846
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,438,613,687,846 is 3346389467676.
Find LCM of 772,438,613,687,846 with Prime Factorization
| 2 | 772, 438, 613, 687, 846 |
| 3 | 386, 219, 613, 687, 423 |
| 386, 73, 613, 229, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 386 x 73 x 613 x 229 x 141 = 3346389467676
Therefore, the lowest common multiple of 772,438,613,687,846 is 3346389467676.
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.
772 x 438 x 613 x 687 x 846 = 120470020836336
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.
772 : 1, 2, 4, 193, 386, 772
438 : 1, 2, 3, 6, 73, 146, 219, 438
613 : 1, 613
687 : 1, 3, 229, 687
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,438,613,687,846, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
438:2x 3x 73
613:613
687:3x 229
846:2x 3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 120470020836336/(1x36)
LCM = 120470020836336/36
LCM = 3346389467676
Thus, we can understand that the LCM of 772,438,613,687,846 is 3346389467676.
