Given numbers are 723,639,651,660

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

The LCM of 723,639,651,660 is 7351912260.

Find LCM of 723,639,651,660 with Prime Factorization

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

3 x 241 x 213 x 217 x 220 = 7351912260

Therefore, the lowest common multiple of 723,639,651,660 is 7351912260.

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.

723 x 639 x 651 x 660 = 198501631020

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.

723 : 1, 3, 241, 723

639 : 1, 3, 9, 71, 213, 639

651 : 1, 3, 7, 21, 31, 93, 217, 651

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,639,651,660, is 3.

Now, the common factors can be found like this.

723:3x 241

639:3x 3x 71

651:3x 7x 31

660:2x 2x 3x 5x 11

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 198501631020/(3x9)

LCM = 198501631020/27

LCM = 7351912260

Thus, we can understand that the LCM of 723,639,651,660 is 7351912260.
