Given numbers are 845,728,871

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

The LCM of 845,728,871 is 3170440.

Find LCM of 845,728,871 with Prime Factorization

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

13 x 65 x 56 x 67 = 3170440

Therefore, the lowest common multiple of 845,728,871 is 3170440.

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.

845 x 728 x 871 = 535804360

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.

845 : 1, 5, 13, 65, 169, 845

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

871 : 1, 13, 67, 871

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,728,871, is 13.

Now, the common factors can be found like this.

845:5x 13x 13

728:2x 2x 2x 7x 13

871:13x 67

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

13 = 13

Therefore, the value for common factors is 13.

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 = 535804360/(13x13)

LCM = 535804360/169

LCM = 3170440

Thus, we can understand that the LCM of 845,728,871 is 3170440.
