Given numbers are 166,221,438,723

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

The LCM of 166,221,438,723 is 1936250394.

Find LCM of 166,221,438,723 with Prime Factorization

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

2 x 3 x 83 x 221 x 73 x 241 = 1936250394

Therefore, the lowest common multiple of 166,221,438,723 is 1936250394.

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.

166 x 221 x 438 x 723 = 11617502364

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.

166 : 1, 2, 83, 166

221 : 1, 13, 17, 221

438 : 1, 2, 3, 6, 73, 146, 219, 438

723 : 1, 3, 241, 723

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 166,221,438,723, is 1.

Now, the common factors can be found like this.

166:2x 83

221:13x 17

438:2x 3x 73

723:3x 241

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 11617502364/(1x6)

LCM = 11617502364/6

LCM = 1936250394

Thus, we can understand that the LCM of 166,221,438,723 is 1936250394.
