The LCM of 327,161,579,742,644 is 2154104652.
Find LCM of 327,161,579,742,644 with Prime Factorization
| 2 | 327, 161, 579, 742, 644 |
| 3 | 327, 161, 579, 371, 322 |
| 7 | 109, 161, 193, 371, 322 |
| 23 | 109, 23, 193, 53, 46 |
| 109, 1, 193, 53, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 109 x 1 x 193 x 53 x 2 = 2154104652
Therefore, the lowest common multiple of 327,161,579,742,644 is 2154104652.
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.
327 x 161 x 579 x 742 x 644 = 14566055656824
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.
327 : 1, 3, 109, 327
161 : 1, 7, 23, 161
579 : 1, 3, 193, 579
742 : 1, 2, 7, 14, 53, 106, 371, 742
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,161,579,742,644, is 1.
Now, the common factors can be found like this.
327:3x 109
161:7x 23
579:3x 193
742:2x 7x 53
644:2x 2x 7x 23
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 7x 7x 23 = 6762
Therefore, the value for common factors is 6762.
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 = 14566055656824/(1x6762)
LCM = 14566055656824/6762
LCM = 2154104652
Thus, we can understand that the LCM of 327,161,579,742,644 is 2154104652.
