Given numbers are 665,286,667,171

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

The LCM of 665,286,667,171 is 1141710570.

Find LCM of 665,286,667,171 with Prime Factorization

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

19 x 35 x 286 x 667 x 9 = 1141710570

Therefore, the lowest common multiple of 665,286,667,171 is 1141710570.

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.

665 x 286 x 667 x 171 = 21692500830

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

286 : 1, 2, 11, 13, 22, 26, 143, 286

667 : 1, 23, 29, 667

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,286,667,171, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

286:2x 11x 13

667:23x 29

171:3x 3x 19

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

19 = 19

Therefore, the value for common factors is 19.

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 = 21692500830/(1x19)

LCM = 21692500830/19

LCM = 1141710570

Thus, we can understand that the LCM of 665,286,667,171 is 1141710570.
