Given numbers are 667,381,196,170

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

The LCM of 667,381,196,170 is 4233755820.

Find LCM of 667,381,196,170 with Prime Factorization

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

2 x 667 x 381 x 98 x 85 = 4233755820

Therefore, the lowest common multiple of 667,381,196,170 is 4233755820.

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.

667 x 381 x 196 x 170 = 8467511640

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.

667 : 1, 23, 29, 667

381 : 1, 3, 127, 381

196 : 1, 2, 4, 7, 14, 28, 49, 98, 196

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,381,196,170, is 1.

Now, the common factors can be found like this.

667:23x 29

381:3x 127

196:2x 2x 7x 7

170:2x 5x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 8467511640/(1x2)

LCM = 8467511640/2

LCM = 4233755820

Thus, we can understand that the LCM of 667,381,196,170 is 4233755820.
