Given numbers are 849,105,646,747

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

The LCM of 849,105,646,747 is 4779776610.

Find LCM of 849,105,646,747 with Prime Factorization

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

3 x 283 x 35 x 646 x 249 = 4779776610

Therefore, the lowest common multiple of 849,105,646,747 is 4779776610.

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.

849 x 105 x 646 x 747 = 43017989490

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.

849 : 1, 3, 283, 849

105 : 1, 3, 5, 7, 15, 21, 35, 105

646 : 1, 2, 17, 19, 34, 38, 323, 646

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 849,105,646,747, is 1.

Now, the common factors can be found like this.

849:3x 283

105:3x 5x 7

646:2x 17x 19

747:3x 3x 83

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 43017989490/(1x9)

LCM = 43017989490/9

LCM = 4779776610

Thus, we can understand that the LCM of 849,105,646,747 is 4779776610.
