Find LCM of 338,978,975,325 with Prime Factorization
| 2 | 338, 978, 975, 325 |
| 3 | 169, 489, 975, 325 |
| 5 | 169, 163, 325, 325 |
| 5 | 169, 163, 65, 65 |
| 13 | 169, 163, 13, 13 |
| 1, 163, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 13 x 1 x 163 x 1 x 13 = 4132050
Therefore, the lowest common multiple of 338,978,975,325 is 4132050.
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.
338 x 978 x 975 x 325 = 104747467500
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.
338 : 1, 2, 13, 26, 169, 338
978 : 1, 2, 3, 6, 163, 326, 489, 978
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
325 : 1, 5, 13, 25, 65, 325
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,978,975,325, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
978:2x 3x 163
975:3x 5x 5x 13
325:5x 5x 13
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 5x 5x 13x 13 = 25350
Therefore, the value for common factors is 25350.
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 = 104747467500/(1x25350)
LCM = 104747467500/25350
LCM = 4132050
Thus, we can understand that the LCM of 338,978,975,325 is 4132050.
