Given numbers are 721,839,309,919

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

The LCM of 721,839,309,919 is 1667761683.

Find LCM of 721,839,309,919 with Prime Factorization

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

103 x 7 x 839 x 3 x 919 = 1667761683

Therefore, the lowest common multiple of 721,839,309,919 is 1667761683.

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 839 x 309 x 919 = 171779453349

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

839 : 1, 839

309 : 1, 3, 103, 309

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,839,309,919, is 1.

Now, the common factors can be found like this.

721:7x 103

839:839

309:3x 103

919:919

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

103 = 103

Therefore, the value for common factors is 103.

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 = 171779453349/(1x103)

LCM = 171779453349/103

LCM = 1667761683

Thus, we can understand that the LCM of 721,839,309,919 is 1667761683.
