Given numbers are 644,950,716,618,872

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

The LCM of 644,950,716,618,872 is 3688480408200.

Find LCM of 644,950,716,618,872 with Prime Factorization

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

2 x 2 x 161 x 475 x 179 x 309 x 218 = 3688480408200

Therefore, the lowest common multiple of 644,950,716,618,872 is 3688480408200.

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 950 x 716 x 618 x 872 = 236062746124800

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

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

716 : 1, 2, 4, 179, 358, 716

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

872 : 1, 2, 4, 8, 109, 218, 436, 872

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,950,716,618,872, is 2.

Now, the common factors can be found like this.

644:2x 2x 7x 23

950:2x 5x 5x 19

716:2x 2x 179

618:2x 3x 103

872:2x 2x 2x 109

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 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 236062746124800/(2x32)

LCM = 236062746124800/64

LCM = 3688480408200

Thus, we can understand that the LCM of 644,950,716,618,872 is 3688480408200.
