Given numbers are 399,572,948,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,572,948,638 is 522870348.
Find LCM of 399,572,948,638 with Prime Factorization
| 2 | 399, 572, 948, 638 |
| 2 | 399, 286, 474, 319 |
| 3 | 399, 143, 237, 319 |
| 11 | 133, 143, 79, 319 |
| 133, 13, 79, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 133 x 13 x 79 x 29 = 522870348
Therefore, the lowest common multiple of 399,572,948,638 is 522870348.
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 572 x 948 x 638 = 138037771872
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
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,572,948,638, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
572:2x 2x 11x 13
948:2x 2x 3x 79
638:2x 11x 29
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 138037771872/(1x264)
LCM = 138037771872/264
LCM = 522870348
Thus, we can understand that the LCM of 399,572,948,638 is 522870348.
