Given numbers are 406,154,858,274,816

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

The LCM of 406,154,858,274,816 is 3245209968.

Find LCM of 406,154,858,274,816 with Prime Factorization

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

2 x 3 x 7 x 11 x 29 x 1 x 13 x 137 x 136 = 3245209968

Therefore, the lowest common multiple of 406,154,858,274,816 is 3245209968.

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.

406 x 154 x 858 x 274 x 816 = 11994296041728

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.

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

154 : 1, 2, 7, 11, 14, 22, 77, 154

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

274 : 1, 2, 137, 274

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 406,154,858,274,816, is 2.

Now, the common factors can be found like this.

406:2x 7x 29

154:2x 7x 11

858:2x 3x 11x 13

274:2x 137

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 2x 3x 7x 11 = 1848

Therefore, the value for common factors is 1848.

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 = 11994296041728/(2x1848)

LCM = 11994296041728/3696

LCM = 3245209968

Thus, we can understand that the LCM of 406,154,858,274,816 is 3245209968.
