Given numbers are 811,689,728

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

The LCM of 811,689,728 is 31291624.

Find LCM of 811,689,728 with Prime Factorization

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

13 x 811 x 53 x 56 = 31291624

Therefore, the lowest common multiple of 811,689,728 is 31291624.

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.

811 x 689 x 728 = 406791112

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.

811 : 1, 811

689 : 1, 13, 53, 689

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,689,728, is 1.

Now, the common factors can be found like this.

811:811

689:13x 53

728:2x 2x 2x 7x 13

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 = 406791112/(1x13)

LCM = 406791112/13

LCM = 31291624

Thus, we can understand that the LCM of 811,689,728 is 31291624.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 734, 571, 250
