Given numbers are 728,907,654,235,688

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

The LCM of 728,907,654,235,688 is 4363678366320.

Find LCM of 728,907,654,235,688 with Prime Factorization

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

2 x 2 x 2 x 91 x 907 x 327 x 235 x 86 = 4363678366320

Therefore, the lowest common multiple of 728,907,654,235,688 is 4363678366320.

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 907 x 654 x 235 x 688 = 69818853861120

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

907 : 1, 907

654 : 1, 2, 3, 6, 109, 218, 327, 654

235 : 1, 5, 47, 235

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,907,654,235,688, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

907:907

654:2x 3x 109

235:5x 47

688:2x 2x 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 2 = 16

Therefore, the value for common factors is 16.

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 = 69818853861120/(1x16)

LCM = 69818853861120/16

LCM = 4363678366320

Thus, we can understand that the LCM of 728,907,654,235,688 is 4363678366320.
