Given numbers are 278,486,346,722,857

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

The LCM of 278,486,346,722,857 is 3615640117434.

Find LCM of 278,486,346,722,857 with Prime Factorization

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

2 x 139 x 243 x 173 x 361 x 857 = 3615640117434

Therefore, the lowest common multiple of 278,486,346,722,857 is 3615640117434.

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.

278 x 486 x 346 x 722 x 857 = 28925120939472

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.

278 : 1, 2, 139, 278

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

346 : 1, 2, 173, 346

722 : 1, 2, 19, 38, 361, 722

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,486,346,722,857, is 1.

Now, the common factors can be found like this.

278:2x 139

486:2x 3x 3x 3x 3x 3

346:2x 173

722:2x 19x 19

857:857

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 28925120939472/(1x8)

LCM = 28925120939472/8

LCM = 3615640117434

Thus, we can understand that the LCM of 278,486,346,722,857 is 3615640117434.
