Given numbers are 394,401,401,644

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

The LCM of 394,401,401,644 is 50874068.

Find LCM of 394,401,401,644 with Prime Factorization

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

2 x 401 x 197 x 1 x 1 x 322 = 50874068

Therefore, the lowest common multiple of 394,401,401,644 is 50874068.

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.

394 x 401 x 401 x 644 = 40801002536

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.

394 : 1, 2, 197, 394

401 : 1, 401

401 : 1, 401

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,401,401,644, is 1.

Now, the common factors can be found like this.

394:2x 197

401:401

401:401

644:2x 2x 7x 23

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

2x 401 = 802

Therefore, the value for common factors is 802.

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 = 40801002536/(1x802)

LCM = 40801002536/802

LCM = 50874068

Thus, we can understand that the LCM of 394,401,401,644 is 50874068.
