Given numbers are 515,721,673,388

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

The LCM of 515,721,673,388 is 941352020.

Find LCM of 515,721,673,388 with Prime Factorization

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

103 x 5 x 7 x 673 x 388 = 941352020

Therefore, the lowest common multiple of 515,721,673,388 is 941352020.

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.

515 x 721 x 673 x 388 = 96959258060

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.

515 : 1, 5, 103, 515

721 : 1, 7, 103, 721

673 : 1, 673

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,721,673,388, is 1.

Now, the common factors can be found like this.

515:5x 103

721:7x 103

673:673

388:2x 2x 97

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 = 96959258060/(1x103)

LCM = 96959258060/103

LCM = 941352020

Thus, we can understand that the LCM of 515,721,673,388 is 941352020.
