Given numbers are 423,418,779,324
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,418,779,324 is 130488732.
Find LCM of 423,418,779,324 with Prime Factorization
2 | 423, 418, 779, 324 |
3 | 423, 209, 779, 162 |
3 | 141, 209, 779, 54 |
19 | 47, 209, 779, 18 |
47, 11, 41, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 47 x 11 x 41 x 18 = 130488732
Therefore, the lowest common multiple of 423,418,779,324 is 130488732.
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.
423 x 418 x 779 x 324 = 44627146344
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.
423 : 1, 3, 9, 47, 141, 423
418 : 1, 2, 11, 19, 22, 38, 209, 418
779 : 1, 19, 41, 779
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,418,779,324, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
418:2x 11x 19
779:19x 41
324:2x 2x 3x 3x 3x 3
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 3x 19 = 342
Therefore, the value for common factors is 342.
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 = 44627146344/(1x342)
LCM = 44627146344/342
LCM = 130488732
Thus, we can understand that the LCM of 423,418,779,324 is 130488732.
