Given numbers are 258,170,166,392

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

The LCM of 258,170,166,392 is 356757240.

Find LCM of 258,170,166,392 with Prime Factorization

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

2 x 129 x 85 x 83 x 196 = 356757240

Therefore, the lowest common multiple of 258,170,166,392 is 356757240.

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 170 x 166 x 392 = 2854057920

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

170 : 1, 2, 5, 10, 17, 34, 85, 170

166 : 1, 2, 83, 166

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,170,166,392, is 2.

Now, the common factors can be found like this.

258:2x 3x 43

170:2x 5x 17

166:2x 83

392:2x 2x 2x 7x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 2854057920/(2x4)

LCM = 2854057920/8

LCM = 356757240

Thus, we can understand that the LCM of 258,170,166,392 is 356757240.
