Given numbers are 342,193,455,207

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 342,193,455,207 is 690752790.

Find LCM of 342,193,455,207 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 3 x 38 x 193 x 455 x 23 = 690752790

Therefore, the lowest common multiple of 342,193,455,207 is 690752790.

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 193 x 455 x 207 = 6216775110

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

193 : 1, 193

455 : 1, 5, 7, 13, 35, 65, 91, 455

207 : 1, 3, 9, 23, 69, 207

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,193,455,207, is 1.

Now, the common factors can be found like this.

342:2x 3x 3x 19

193:193

455:5x 7x 13

207:3x 3x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 6216775110/(1x9)

LCM = 6216775110/9

LCM = 690752790

Thus, we can understand that the LCM of 342,193,455,207 is 690752790.
