Given numbers are 417,278,435,801,161

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

The LCM of 417,278,435,801,161 is 5198417910.

Find LCM of 417,278,435,801,161 with Prime Factorization

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

3 x 139 x 1 x 2 x 145 x 267 x 161 = 5198417910

Therefore, the lowest common multiple of 417,278,435,801,161 is 5198417910.

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.

417 x 278 x 435 x 801 x 161 = 6503220805410

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.

417 : 1, 3, 139, 417

278 : 1, 2, 139, 278

435 : 1, 3, 5, 15, 29, 87, 145, 435

801 : 1, 3, 9, 89, 267, 801

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,278,435,801,161, is 1.

Now, the common factors can be found like this.

417:3x 139

278:2x 139

435:3x 5x 29

801:3x 3x 89

161:7x 23

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

3x 3x 139 = 1251

Therefore, the value for common factors is 1251.

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 = 6503220805410/(1x1251)

LCM = 6503220805410/1251

LCM = 5198417910

Thus, we can understand that the LCM of 417,278,435,801,161 is 5198417910.
