Given numbers are 130,668,406,816

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

The LCM of 130,668,406,816 is 1798109040.

Find LCM of 130,668,406,816 with Prime Factorization

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

2 x 2 x 65 x 167 x 203 x 204 = 1798109040

Therefore, the lowest common multiple of 130,668,406,816 is 1798109040.

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.

130 x 668 x 406 x 816 = 28769744640

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.

130 : 1, 2, 5, 10, 13, 26, 65, 130

668 : 1, 2, 4, 167, 334, 668

406 : 1, 2, 7, 14, 29, 58, 203, 406

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,668,406,816, is 2.

Now, the common factors can be found like this.

130:2x 5x 13

668:2x 2x 167

406:2x 7x 29

816:2x 2x 2x 2x 3x 17

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 = 28769744640/(2x8)

LCM = 28769744640/16

LCM = 1798109040

Thus, we can understand that the LCM of 130,668,406,816 is 1798109040.
