Given numbers are 406,128,145,266

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

The LCM of 406,128,145,266 is 2468480.

Find LCM of 406,128,145,266 with Prime Factorization

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

2 x 7 x 29 x 1 x 64 x 5 x 19 = 2468480

Therefore, the lowest common multiple of 406,128,145,266 is 2468480.

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.

406 x 128 x 145 x 266 = 2004405760

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.

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

128 : 1, 2, 4, 8, 16, 32, 64, 128

145 : 1, 5, 29, 145

266 : 1, 2, 7, 14, 19, 38, 133, 266

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,128,145,266, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

128:2x 2x 2x 2x 2x 2x 2

145:5x 29

266:2x 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.

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 = 2004405760/(1x812)

LCM = 2004405760/812

LCM = 2468480

Thus, we can understand that the LCM of 406,128,145,266 is 2468480.
