Given numbers are 401,90,485

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

The LCM of 401,90,485 is 3500730.

Find LCM of 401,90,485 with Prime Factorization

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

5 x 401 x 18 x 97 = 3500730

Therefore, the lowest common multiple of 401,90,485 is 3500730.

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 90 x 485 = 17503650

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

90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,90,485, is 1.

Now, the common factors can be found like this.

401:401

90:2x 3x 3x 5

485:5x 97

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

5 = 5

Therefore, the value for common factors is 5.

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 = 17503650/(1x5)

LCM = 17503650/5

LCM = 3500730

Thus, we can understand that the LCM of 401,90,485 is 3500730.

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

• LCM of 614, 30, 753
• LCM of 299, 99, 600
