Given numbers are 399,463,884,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,463,884,380 is 816537540.
Find LCM of 399,463,884,380 with Prime Factorization
| 2 | 399, 463, 884, 380 |
| 2 | 399, 463, 442, 190 |
| 19 | 399, 463, 221, 95 |
| 21, 463, 221, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 21 x 463 x 221 x 5 = 816537540
Therefore, the lowest common multiple of 399,463,884,380 is 816537540.
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.
399 x 463 x 884 x 380 = 62056853040
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
463 : 1, 463
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,463,884,380, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
463:463
884:2x 2x 13x 17
380:2x 2x 5x 19
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 19 = 76
Therefore, the value for common factors is 76.
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 = 62056853040/(1x76)
LCM = 62056853040/76
LCM = 816537540
Thus, we can understand that the LCM of 399,463,884,380 is 816537540.
