Given numbers are 663,321,335,749,406

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

The LCM of 663,321,335,749,406 is 9648685410.

Find LCM of 663,321,335,749,406 with Prime Factorization

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

3 x 7 x 107 x 221 x 1 x 335 x 1 x 58 = 9648685410

Therefore, the lowest common multiple of 663,321,335,749,406 is 9648685410.

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.

663 x 321 x 335 x 749 x 406 = 21680596116270

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

321 : 1, 3, 107, 321

335 : 1, 5, 67, 335

749 : 1, 7, 107, 749

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 663,321,335,749,406, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

321:3x 107

335:5x 67

749:7x 107

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.

3x 7x 107 = 2247

Therefore, the value for common factors is 2247.

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 = 21680596116270/(1x2247)

LCM = 21680596116270/2247

LCM = 9648685410

Thus, we can understand that the LCM of 663,321,335,749,406 is 9648685410.
