Given numbers are 728,307,692,857

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

The LCM of 728,307,692,857 is 33135740456.

Find LCM of 728,307,692,857 with Prime Factorization

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

2 x 2 x 182 x 307 x 173 x 857 = 33135740456

Therefore, the lowest common multiple of 728,307,692,857 is 33135740456.

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.

728 x 307 x 692 x 857 = 132542961824

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

307 : 1, 307

692 : 1, 2, 4, 173, 346, 692

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,307,692,857, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

307:307

692:2x 2x 173

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 2 = 4

Therefore, the value for common factors is 4.

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 = 132542961824/(1x4)

LCM = 132542961824/4

LCM = 33135740456

Thus, we can understand that the LCM of 728,307,692,857 is 33135740456.
