Given numbers are 644,402,729,173,618

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

The LCM of 644,402,729,173,618 is 560494720548.

Find LCM of 644,402,729,173,618 with Prime Factorization

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

2 x 3 x 322 x 67 x 243 x 173 x 103 = 560494720548

Therefore, the lowest common multiple of 644,402,729,173,618 is 560494720548.

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.

644 x 402 x 729 x 173 x 618 = 20177809939728

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

402 : 1, 2, 3, 6, 67, 134, 201, 402

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

173 : 1, 173

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,402,729,173,618, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

402:2x 3x 67

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

173:173

618:2x 3x 103

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 20177809939728/(1x36)

LCM = 20177809939728/36

LCM = 560494720548

Thus, we can understand that the LCM of 644,402,729,173,618 is 560494720548.
