Given numbers are 159,646,221,682

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

The LCM of 159,646,221,682 is 455331162.

Find LCM of 159,646,221,682 with Prime Factorization

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

2 x 17 x 159 x 19 x 13 x 341 = 455331162

Therefore, the lowest common multiple of 159,646,221,682 is 455331162.

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.

159 x 646 x 221 x 682 = 15481259508

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.

159 : 1, 3, 53, 159

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

221 : 1, 13, 17, 221

682 : 1, 2, 11, 22, 31, 62, 341, 682

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,646,221,682, is 1.

Now, the common factors can be found like this.

159:3x 53

646:2x 17x 19

221:13x 17

682:2x 11x 31

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 15481259508/(1x34)

LCM = 15481259508/34

LCM = 455331162

Thus, we can understand that the LCM of 159,646,221,682 is 455331162.
