Given numbers are 869,857,128,729,297

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

The LCM of 869,857,128,729,297 is 69492525696.

Find LCM of 869,857,128,729,297 with Prime Factorization

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

3 x 3 x 3 x 11 x 79 x 857 x 128 x 27 x 1 = 69492525696

Therefore, the lowest common multiple of 869,857,128,729,297 is 69492525696.

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.

869 x 857 x 128 x 729 x 297 = 20639280131712

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.

869 : 1, 11, 79, 869

857 : 1, 857

128 : 1, 2, 4, 8, 16, 32, 64, 128

729 : 1, 3, 9, 27, 81, 243, 729

297 : 1, 3, 9, 11, 27, 33, 99, 297

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,857,128,729,297, is 1.

Now, the common factors can be found like this.

869:11x 79

857:857

128:2x 2x 2x 2x 2x 2x 2

729:3x 3x 3x 3x 3x 3

297:3x 3x 3x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 3x 11 = 297

Therefore, the value for common factors is 297.

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 = 20639280131712/(1x297)

LCM = 20639280131712/297

LCM = 69492525696

Thus, we can understand that the LCM of 869,857,128,729,297 is 69492525696.
