Given numbers are 169,668,890,865

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

The LCM of 169,668,890,865 is 8690990620.

Find LCM of 169,668,890,865 with Prime Factorization

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

2 x 5 x 169 x 334 x 89 x 173 = 8690990620

Therefore, the lowest common multiple of 169,668,890,865 is 8690990620.

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.

169 x 668 x 890 x 865 = 86909906200

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.

169 : 1, 13, 169

668 : 1, 2, 4, 167, 334, 668

890 : 1, 2, 5, 10, 89, 178, 445, 890

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,668,890,865, is 1.

Now, the common factors can be found like this.

169:13x 13

668:2x 2x 167

890:2x 5x 89

865:5x 173

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 86909906200/(1x10)

LCM = 86909906200/10

LCM = 8690990620

Thus, we can understand that the LCM of 169,668,890,865 is 8690990620.
