Given numbers are 258,181,156,102

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

The LCM of 258,181,156,102 is 20640516.

Find LCM of 258,181,156,102 with Prime Factorization

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

2 x 3 x 43 x 181 x 26 x 17 = 20640516

Therefore, the lowest common multiple of 258,181,156,102 is 20640516.

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.

258 x 181 x 156 x 102 = 743058576

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.

258 : 1, 2, 3, 6, 43, 86, 129, 258

181 : 1, 181

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

102 : 1, 2, 3, 6, 17, 34, 51, 102

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,181,156,102, is 1.

Now, the common factors can be found like this.

258:2x 3x 43

181:181

156:2x 2x 3x 13

102:2x 3x 17

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 743058576/(1x36)

LCM = 743058576/36

LCM = 20640516

Thus, we can understand that the LCM of 258,181,156,102 is 20640516.
