Given numbers are 721,485,729,280

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

The LCM of 721,485,729,280 is 2039362920.

Find LCM of 721,485,729,280 with Prime Factorization

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

5 x 7 x 103 x 97 x 729 x 8 = 2039362920

Therefore, the lowest common multiple of 721,485,729,280 is 2039362920.

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 485 x 729 x 280 = 71377702200

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

485 : 1, 5, 97, 485

729 : 1, 3, 9, 27, 81, 243, 729

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,485,729,280, is 1.

Now, the common factors can be found like this.

721:7x 103

485:5x 97

729:3x 3x 3x 3x 3x 3

280:2x 2x 2x 5x 7

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

5x 7 = 35

Therefore, the value for common factors is 35.

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 = 71377702200/(1x35)

LCM = 71377702200/35

LCM = 2039362920

Thus, we can understand that the LCM of 721,485,729,280 is 2039362920.
