Given numbers are 361,342,131,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,342,131,399 is 5958666.
Find LCM of 361,342,131,399 with Prime Factorization
| 3 | 361, 342, 131, 399 |
| 19 | 361, 114, 131, 133 |
| 19, 6, 131, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 19 x 6 x 131 x 7 = 5958666
Therefore, the lowest common multiple of 361,342,131,399 is 5958666.
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.
361 x 342 x 131 x 399 = 6453235278
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.
361 : 1, 19, 361
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
131 : 1, 131
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,342,131,399, is 1.
Now, the common factors can be found like this.
361:19x 19
342:2x 3x 3x 19
131:131
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 19 = 1083
Therefore, the value for common factors is 1083.
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 = 6453235278/(1x1083)
LCM = 6453235278/1083
LCM = 5958666
Thus, we can understand that the LCM of 361,342,131,399 is 5958666.
