Given numbers are 278,344,646,862

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

The LCM of 278,344,646,862 is 6656608808.

Find LCM of 278,344,646,862 with Prime Factorization

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

2 x 139 x 172 x 323 x 431 = 6656608808

Therefore, the lowest common multiple of 278,344,646,862 is 6656608808.

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 344 x 646 x 862 = 53252870464

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

344 : 1, 2, 4, 8, 43, 86, 172, 344

646 : 1, 2, 17, 19, 34, 38, 323, 646

862 : 1, 2, 431, 862

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,344,646,862, is 2.

Now, the common factors can be found like this.

278:2x 139

344:2x 2x 2x 43

646:2x 17x 19

862:2x 431

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 53252870464/(2x4)

LCM = 53252870464/8

LCM = 6656608808

Thus, we can understand that the LCM of 278,344,646,862 is 6656608808.
