Given numbers are 842,873,864,730,172

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

The LCM of 842,873,864,730,172 is 553769321760.

Find LCM of 842,873,864,730,172 with Prime Factorization

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

2 x 2 x 3 x 3 x 421 x 97 x 24 x 365 x 43 = 553769321760

Therefore, the lowest common multiple of 842,873,864,730,172 is 553769321760.

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.

842 x 873 x 864 x 730 x 172 = 79742782333440

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.

842 : 1, 2, 421, 842

873 : 1, 3, 9, 97, 291, 873

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

730 : 1, 2, 5, 10, 73, 146, 365, 730

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,873,864,730,172, is 1.

Now, the common factors can be found like this.

842:2x 421

873:3x 3x 97

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

730:2x 5x 73

172:2x 2x 43

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 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 79742782333440/(1x144)

LCM = 79742782333440/144

LCM = 553769321760

Thus, we can understand that the LCM of 842,873,864,730,172 is 553769321760.
