Given numbers are 853,170,391,664

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

The LCM of 853,170,391,664 is 1107296360.

Find LCM of 853,170,391,664 with Prime Factorization

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

2 x 17 x 853 x 5 x 23 x 332 = 1107296360

Therefore, the lowest common multiple of 853,170,391,664 is 1107296360.

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.

853 x 170 x 391 x 664 = 37648076240

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.

853 : 1, 853

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

391 : 1, 17, 23, 391

664 : 1, 2, 4, 8, 83, 166, 332, 664

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,170,391,664, is 1.

Now, the common factors can be found like this.

853:853

170:2x 5x 17

391:17x 23

664:2x 2x 2x 83

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 37648076240/(1x34)

LCM = 37648076240/34

LCM = 1107296360

Thus, we can understand that the LCM of 853,170,391,664 is 1107296360.
