Given numbers are 142,166,203,406

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

The LCM of 142,166,203,406 is 2392558.

Find LCM of 142,166,203,406 with Prime Factorization

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

2 x 7 x 29 x 71 x 83 x 1 x 1 = 2392558

Therefore, the lowest common multiple of 142,166,203,406 is 2392558.

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.

142 x 166 x 203 x 406 = 1942757096

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.

142 : 1, 2, 71, 142

166 : 1, 2, 83, 166

203 : 1, 7, 29, 203

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,166,203,406, is 1.

Now, the common factors can be found like this.

142:2x 71

166:2x 83

203:7x 29

406:2x 7x 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 7x 29 = 812

Therefore, the value for common factors is 812.

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 = 1942757096/(1x812)

LCM = 1942757096/812

LCM = 2392558

Thus, we can understand that the LCM of 142,166,203,406 is 2392558.
