Given numbers are 816,186,812,857

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

The LCM of 816,186,812,857 is 4400770416.

Find LCM of 816,186,812,857 with Prime Factorization

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

2 x 2 x 3 x 68 x 31 x 203 x 857 = 4400770416

Therefore, the lowest common multiple of 816,186,812,857 is 4400770416.

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.

816 x 186 x 812 x 857 = 105618489984

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.

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

186 : 1, 2, 3, 6, 31, 62, 93, 186

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,186,812,857, is 1.

Now, the common factors can be found like this.

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

186:2x 3x 31

812:2x 2x 7x 29

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 105618489984/(1x24)

LCM = 105618489984/24

LCM = 4400770416

Thus, we can understand that the LCM of 816,186,812,857 is 4400770416.
