Given numbers are 721,728,503,581,757

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

The LCM of 721,728,503,581,757 is 2369793811112.

Find LCM of 721,728,503,581,757 with Prime Factorization

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

7 x 103 x 104 x 503 x 83 x 757 = 2369793811112

Therefore, the lowest common multiple of 721,728,503,581,757 is 2369793811112.

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 728 x 503 x 581 x 757 = 116119896744488

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

503 : 1, 503

581 : 1, 7, 83, 581

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,728,503,581,757, is 1.

Now, the common factors can be found like this.

721:7x 103

728:2x 2x 2x 7x 13

503:503

581:7x 83

757:757

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 116119896744488/(1x49)

LCM = 116119896744488/49

LCM = 2369793811112

Thus, we can understand that the LCM of 721,728,503,581,757 is 2369793811112.
