Given numbers are 449,721,721,943

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

The LCM of 449,721,721,943 is 305276447.

Find LCM of 449,721,721,943 with Prime Factorization

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

7 x 103 x 449 x 1 x 1 x 943 = 305276447

Therefore, the lowest common multiple of 449,721,721,943 is 305276447.

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.

449 x 721 x 721 x 943 = 220104318287

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.

449 : 1, 449

721 : 1, 7, 103, 721

721 : 1, 7, 103, 721

943 : 1, 23, 41, 943

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,721,721,943, is 1.

Now, the common factors can be found like this.

449:449

721:7x 103

721:7x 103

943:23x 41

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

7x 103 = 721

Therefore, the value for common factors is 721.

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 = 220104318287/(1x721)

LCM = 220104318287/721

LCM = 305276447

Thus, we can understand that the LCM of 449,721,721,943 is 305276447.
