The LCM of 319,384,400,991 is 3034838400.
Find LCM of 319,384,400,991 with Prime Factorization
| 2 | 319, 384, 400, 991 |
| 2 | 319, 192, 200, 991 |
| 2 | 319, 96, 100, 991 |
| 2 | 319, 48, 50, 991 |
| 319, 24, 25, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 319 x 24 x 25 x 991 = 3034838400
Therefore, the lowest common multiple of 319,384,400,991 is 3034838400.
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.
319 x 384 x 400 x 991 = 48557414400
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.
319 : 1, 11, 29, 319
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,384,400,991, is 1.
Now, the common factors can be found like this.
319:11x 29
384:2x 2x 2x 2x 2x 2x 2x 3
400:2x 2x 2x 2x 5x 5
991:991
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 2 = 16
Therefore, the value for common factors is 16.
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 = 48557414400/(1x16)
LCM = 48557414400/16
LCM = 3034838400
Thus, we can understand that the LCM of 319,384,400,991 is 3034838400.
