Given numbers are 721,857,669,153,547

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

The LCM of 721,857,669,153,547 is 11531869175421.

Find LCM of 721,857,669,153,547 with Prime Factorization

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

3 x 721 x 857 x 223 x 51 x 547 = 11531869175421

Therefore, the lowest common multiple of 721,857,669,153,547 is 11531869175421.

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 857 x 669 x 153 x 547 = 34595607526263

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

857 : 1, 857

669 : 1, 3, 223, 669

153 : 1, 3, 9, 17, 51, 153

547 : 1, 547

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,857,669,153,547, is 1.

Now, the common factors can be found like this.

721:7x 103

857:857

669:3x 223

153:3x 3x 17

547:547

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

3 = 3

Therefore, the value for common factors is 3.

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 = 34595607526263/(1x3)

LCM = 34595607526263/3

LCM = 11531869175421

Thus, we can understand that the LCM of 721,857,669,153,547 is 11531869175421.
