The LCM of 336,872,168,838 is 15345456.
Find LCM of 336,872,168,838 with Prime Factorization
| 2 | 336, 872, 168, 838 |
| 2 | 168, 436, 84, 419 |
| 2 | 42, 218, 84, 419 |
| 3 | 21, 109, 42, 419 |
| 7 | 7, 109, 14, 419 |
| 1, 109, 2, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 1 x 109 x 2 x 419 = 15345456
Therefore, the lowest common multiple of 336,872,168,838 is 15345456.
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.
336 x 872 x 168 x 838 = 41248585728
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.
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
872 : 1, 2, 4, 8, 109, 218, 436, 872
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
838 : 1, 2, 419, 838
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 336,872,168,838, is 2.
Now, the common factors can be found like this.
336:2x 2x 2x 2x 3x 7
872:2x 2x 2x 109
168:2x 2x 2x 3x 7
838:2x 419
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 2x 2x 2x 2x 3x 7 = 1344
Therefore, the value for common factors is 1344.
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 = 41248585728/(2x1344)
LCM = 41248585728/2688
LCM = 15345456
Thus, we can understand that the LCM of 336,872,168,838 is 15345456.
