Given numbers are 401,130,221

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

The LCM of 401,130,221 is 886210.

Find LCM of 401,130,221 with Prime Factorization

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

13 x 401 x 10 x 17 = 886210

Therefore, the lowest common multiple of 401,130,221 is 886210.

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 130 x 221 = 11520730

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

130 : 1, 2, 5, 10, 13, 26, 65, 130

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,130,221, is 1.

Now, the common factors can be found like this.

401:401

130:2x 5x 13

221:13x 17

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 = 11520730/(1x13)

LCM = 11520730/13

LCM = 886210

Thus, we can understand that the LCM of 401,130,221 is 886210.

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

• LCM of 332, 405, 804
• LCM of 440, 854, 461
