Calculate the LCM of 405,661,416,802

Given numbers are 405,661,416,802

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

The LCM of 405,661,416,802 is 44657477280.

Find LCM of 405,661,416,802 with Prime Factorization


2 405, 661, 416, 802
405, 661, 208, 401

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

2 x 405 x 661 x 208 x 401 = 44657477280

Therefore, the lowest common multiple of 405,661,416,802 is 44657477280.

LCM Formula to Find Lowest Common Multiple of 405,661,416,802

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.

405 x 661 x 416 x 802 = 89314954560

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.

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

661 : 1, 661

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

802 : 1, 2, 401, 802

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,661,416,802, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

661:661

416:2x 2x 2x 2x 2x 13

802:2x 401

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

2 = 2

Therefore, the value for common factors is 2.

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 = 89314954560/(1x2)

LCM = 89314954560/2

LCM = 44657477280

Thus, we can understand that the LCM of 405,661,416,802 is 44657477280.
