Given numbers are 823,401,802,621

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

The LCM of 823,401,802,621 is 409888566.

Find LCM of 823,401,802,621 with Prime Factorization

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

401 x 823 x 1 x 2 x 621 = 409888566

Therefore, the lowest common multiple of 823,401,802,621 is 409888566.

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.

823 x 401 x 802 x 621 = 164365314966

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.

823 : 1, 823

401 : 1, 401

802 : 1, 2, 401, 802

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,401,802,621, is 1.

Now, the common factors can be found like this.

823:823

401:401

802:2x 401

621:3x 3x 3x 23

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

401 = 401

Therefore, the value for common factors is 401.

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 = 164365314966/(1x401)

LCM = 164365314966/401

LCM = 409888566

Thus, we can understand that the LCM of 823,401,802,621 is 409888566.
