Given numbers are 721,816,845,309

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

The LCM of 721,816,845,309 is 497143920.

Find LCM of 721,816,845,309 with Prime Factorization

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

3 x 103 x 7 x 272 x 845 x 1 = 497143920

Therefore, the lowest common multiple of 721,816,845,309 is 497143920.

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.

721 x 816 x 845 x 309 = 153617471280

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.

721 : 1, 7, 103, 721

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

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

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,816,845,309, is 1.

Now, the common factors can be found like this.

721:7x 103

816:2x 2x 2x 2x 3x 17

845:5x 13x 13

309:3x 103

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

3x 103 = 309

Therefore, the value for common factors is 309.

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 = 153617471280/(1x309)

LCM = 153617471280/309

LCM = 497143920

Thus, we can understand that the LCM of 721,816,845,309 is 497143920.
