Given numbers are 864,924,669,306,721

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

The LCM of 864,924,669,306,721 is 25977387744.

Find LCM of 864,924,669,306,721 with Prime Factorization

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

2 x 2 x 3 x 3 x 7 x 24 x 11 x 223 x 17 x 103 = 25977387744

Therefore, the lowest common multiple of 864,924,669,306,721 is 25977387744.

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 924 x 669 x 306 x 721 = 117833430806784

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

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

669 : 1, 3, 223, 669

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,924,669,306,721, is 1.

Now, the common factors can be found like this.

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

924:2x 2x 3x 7x 11

669:3x 223

306:2x 3x 3x 17

721:7x 103

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 3x 3x 3x 7 = 4536

Therefore, the value for common factors is 4536.

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 = 117833430806784/(1x4536)

LCM = 117833430806784/4536

LCM = 25977387744

Thus, we can understand that the LCM of 864,924,669,306,721 is 25977387744.
