Given numbers are 401,647,401,205

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

The LCM of 401,647,401,205 is 53186635.

Find LCM of 401,647,401,205 with Prime Factorization

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

401 x 1 x 647 x 1 x 205 = 53186635

Therefore, the lowest common multiple of 401,647,401,205 is 53186635.

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.

401 x 647 x 401 x 205 = 21327840635

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.

401 : 1, 401

647 : 1, 647

401 : 1, 401

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,647,401,205, is 1.

Now, the common factors can be found like this.

401:401

647:647

401:401

205:5x 41

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 = 21327840635/(1x401)

LCM = 21327840635/401

LCM = 53186635

Thus, we can understand that the LCM of 401,647,401,205 is 53186635.
