Given numbers are 671,33,221

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

The LCM of 671,33,221 is 444873.

Find LCM of 671,33,221 with Prime Factorization

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

11 x 61 x 3 x 221 = 444873

Therefore, the lowest common multiple of 671,33,221 is 444873.

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.

671 x 33 x 221 = 4893603

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.

671 : 1, 11, 61, 671

33 : 1, 3, 11, 33

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,33,221, is 1.

Now, the common factors can be found like this.

671:11x 61

33:3x 11

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.

11 = 11

Therefore, the value for common factors is 11.

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 = 4893603/(1x11)

LCM = 4893603/11

LCM = 444873

Thus, we can understand that the LCM of 671,33,221 is 444873.

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

• LCM of 976, 54, 220
