Given numbers are 864,646,917,812

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

The LCM of 864,646,917,812 is 7421361696.

Find LCM of 864,646,917,812 with Prime Factorization

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

2 x 2 x 7 x 216 x 323 x 131 x 29 = 7421361696

Therefore, the lowest common multiple of 864,646,917,812 is 7421361696.

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.

864 x 646 x 917 x 812 = 415596254976

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.

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

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

917 : 1, 7, 131, 917

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,646,917,812, is 1.

Now, the common factors can be found like this.

864:2x 2x 2x 2x 2x 3x 3x 3

646:2x 17x 19

917:7x 131

812:2x 2x 7x 29

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 7 = 56

Therefore, the value for common factors is 56.

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 = 415596254976/(1x56)

LCM = 415596254976/56

LCM = 7421361696

Thus, we can understand that the LCM of 864,646,917,812 is 7421361696.
