Given numbers are 641,168,476,698,406

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

The LCM of 641,168,476,698,406 is 18528474216.

Find LCM of 641,168,476,698,406 with Prime Factorization

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

2 x 2 x 7 x 641 x 6 x 17 x 349 x 29 = 18528474216

Therefore, the lowest common multiple of 641,168,476,698,406 is 18528474216.

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.

641 x 168 x 476 x 698 x 406 = 14526323785344

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.

641 : 1, 641

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

698 : 1, 2, 349, 698

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 641,168,476,698,406, is 1.

Now, the common factors can be found like this.

641:641

168:2x 2x 2x 3x 7

476:2x 2x 7x 17

698:2x 349

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 2x 2x 7x 7 = 784

Therefore, the value for common factors is 784.

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 = 14526323785344/(1x784)

LCM = 14526323785344/784

LCM = 18528474216

Thus, we can understand that the LCM of 641,168,476,698,406 is 18528474216.
