Given numbers are 999,221,143,401

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

The LCM of 999,221,143,401 is 973856169.

Find LCM of 999,221,143,401 with Prime Factorization

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

13 x 999 x 17 x 11 x 401 = 973856169

Therefore, the lowest common multiple of 999,221,143,401 is 973856169.

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.

999 x 221 x 143 x 401 = 12660130197

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.

999 : 1, 3, 9, 27, 37, 111, 333, 999

221 : 1, 13, 17, 221

143 : 1, 11, 13, 143

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 999,221,143,401, is 1.

Now, the common factors can be found like this.

999:3x 3x 3x 37

221:13x 17

143:11x 13

401:401

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

13 = 13

Therefore, the value for common factors is 13.

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 = 12660130197/(1x13)

LCM = 12660130197/13

LCM = 973856169

Thus, we can understand that the LCM of 999,221,143,401 is 973856169.
