Given numbers are 669,401,401

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

The LCM of 669,401,401 is 268269.

Find LCM of 669,401,401 with Prime Factorization

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

401 x 669 x 1 x 1 = 268269

Therefore, the lowest common multiple of 669,401,401 is 268269.

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.

669 x 401 x 401 = 107575869

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.

669 : 1, 3, 223, 669

401 : 1, 401

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,401,401, is 1.

Now, the common factors can be found like this.

669:3x 223

401:401

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.

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 = 107575869/(1x401)

LCM = 107575869/401

LCM = 268269

Thus, we can understand that the LCM of 669,401,401 is 268269.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 304, 482, 367
