Find LCM of 161,138,462,872,449 with Prime Factorization
2 | 161, 138, 462, 872, 449 |
3 | 161, 69, 231, 436, 449 |
7 | 161, 23, 77, 436, 449 |
23 | 23, 23, 11, 436, 449 |
1, 1, 11, 436, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 1 x 1 x 11 x 436 x 449 = 2080188264
Therefore, the lowest common multiple of 161,138,462,872,449 is 2080188264.
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.
161 x 138 x 462 x 872 x 449 = 4018923726048
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.
161 : 1, 7, 23, 161
138 : 1, 2, 3, 6, 23, 46, 69, 138
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
872 : 1, 2, 4, 8, 109, 218, 436, 872
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,138,462,872,449, is 1.
Now, the common factors can be found like this.
161:7x 23
138:2x 3x 23
462:2x 3x 7x 11
872:2x 2x 2x 109
449:449
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 7x 23 = 1932
Therefore, the value for common factors is 1932.
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 = 4018923726048/(1x1932)
LCM = 4018923726048/1932
LCM = 2080188264
Thus, we can understand that the LCM of 161,138,462,872,449 is 2080188264.
