Given numbers are 644,856,229,173

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

The LCM of 644,856,229,173 is 5459856472.

Find LCM of 644,856,229,173 with Prime Factorization

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

2 x 2 x 161 x 214 x 229 x 173 = 5459856472

Therefore, the lowest common multiple of 644,856,229,173 is 5459856472.

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 856 x 229 x 173 = 21839425888

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

856 : 1, 2, 4, 8, 107, 214, 428, 856

229 : 1, 229

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,856,229,173, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

856:2x 2x 2x 107

229:229

173:173

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 21839425888/(1x4)

LCM = 21839425888/4

LCM = 5459856472

Thus, we can understand that the LCM of 644,856,229,173 is 5459856472.
