Calculate the LCM of 406,982,845,405

Given numbers are 406,982,845,405

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

The LCM of 406,982,845,405 is 13644236970.

Find LCM of 406,982,845,405 with Prime Factorization


2 406, 982, 845, 405
5 203, 491, 845, 405
203, 491, 169, 81

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

2 x 5 x 203 x 491 x 169 x 81 = 13644236970

Therefore, the lowest common multiple of 406,982,845,405 is 13644236970.

LCM Formula to Find Lowest Common Multiple of 406,982,845,405

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 982 x 845 x 405 = 136442369700

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

982 : 1, 2, 491, 982

845 : 1, 5, 13, 65, 169, 845

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,982,845,405, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

982:2x 491

845:5x 13x 13

405:3x 3x 3x 3x 5

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 136442369700/(1x10)

LCM = 136442369700/10

LCM = 13644236970

Thus, we can understand that the LCM of 406,982,845,405 is 13644236970.
