Given numbers are 145,406,406,849

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

The LCM of 145,406,406,849 is 1723470.

Find LCM of 145,406,406,849 with Prime Factorization

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

2 x 7 x 29 x 5 x 1 x 1 x 849 = 1723470

Therefore, the lowest common multiple of 145,406,406,849 is 1723470.

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.

145 x 406 x 406 x 849 = 20292135780

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.

145 : 1, 5, 29, 145

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

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

849 : 1, 3, 283, 849

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,406,406,849, is 1.

Now, the common factors can be found like this.

145:5x 29

406:2x 7x 29

406:2x 7x 29

849:3x 283

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

2x 7x 29x 29 = 11774

Therefore, the value for common factors is 11774.

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 = 20292135780/(1x11774)

LCM = 20292135780/11774

LCM = 1723470

Thus, we can understand that the LCM of 145,406,406,849 is 1723470.
