Given numbers are 221,156,187,404

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

The LCM of 221,156,187,404 is 2946372.

Find LCM of 221,156,187,404 with Prime Factorization

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

2 x 2 x 13 x 17 x 1 x 3 x 11 x 101 = 2946372

Therefore, the lowest common multiple of 221,156,187,404 is 2946372.

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.

221 x 156 x 187 x 404 = 2604592848

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.

221 : 1, 13, 17, 221

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

187 : 1, 11, 17, 187

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,156,187,404, is 1.

Now, the common factors can be found like this.

221:13x 17

156:2x 2x 3x 13

187:11x 17

404:2x 2x 101

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

2x 2x 13x 17 = 884

Therefore, the value for common factors is 884.

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 = 2604592848/(1x884)

LCM = 2604592848/884

LCM = 2946372

Thus, we can understand that the LCM of 221,156,187,404 is 2946372.
