Given numbers are 161,299,779,915,288

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

The LCM of 161,299,779,915,288 is 143218464480.

Find LCM of 161,299,779,915,288 with Prime Factorization

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

3 x 23 x 7 x 13 x 779 x 305 x 96 = 143218464480

Therefore, the lowest common multiple of 161,299,779,915,288 is 143218464480.

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.

161 x 299 x 779 x 915 x 288 = 9882074049120

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.

161 : 1, 7, 23, 161

299 : 1, 13, 23, 299

779 : 1, 19, 41, 779

915 : 1, 3, 5, 15, 61, 183, 305, 915

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,299,779,915,288, is 1.

Now, the common factors can be found like this.

161:7x 23

299:13x 23

779:19x 41

915:3x 5x 61

288:2x 2x 2x 2x 2x 3x 3

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

3x 23 = 69

Therefore, the value for common factors is 69.

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 = 9882074049120/(1x69)

LCM = 9882074049120/69

LCM = 143218464480

Thus, we can understand that the LCM of 161,299,779,915,288 is 143218464480.
