Given numbers are 342,442,722,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 342,442,722,144 is 11488464.
Find LCM of 342,442,722,144 with Prime Factorization
2 | 342, 442, 722, 144 |
3 | 171, 221, 361, 72 |
3 | 57, 221, 361, 24 |
19 | 19, 221, 361, 8 |
1, 221, 19, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 1 x 221 x 19 x 8 = 11488464
Therefore, the lowest common multiple of 342,442,722,144 is 11488464.
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.
342 x 442 x 722 x 144 = 15716218752
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
442 : 1, 2, 13, 17, 26, 34, 221, 442
722 : 1, 2, 19, 38, 361, 722
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,442,722,144, is 2.
Now, the common factors can be found like this.
342:2x 3x 3x 19
442:2x 13x 17
722:2x 19x 19
144:2x 2x 2x 2x 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 2x 3x 3x 19 = 684
Therefore, the value for common factors is 684.
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 = 15716218752/(2x684)
LCM = 15716218752/1368
LCM = 11488464
Thus, we can understand that the LCM of 342,442,722,144 is 11488464.
