Given numbers are 644,263,284,313,176

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

The LCM of 644,263,284,313,176 is 165613974064.

Find LCM of 644,263,284,313,176 with Prime Factorization

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

2 x 2 x 161 x 263 x 71 x 313 x 44 = 165613974064

Therefore, the lowest common multiple of 644,263,284,313,176 is 165613974064.

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 263 x 284 x 313 x 176 = 2649823585024

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

263 : 1, 263

284 : 1, 2, 4, 71, 142, 284

313 : 1, 313

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,263,284,313,176, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

263:263

284:2x 2x 71

313:313

176:2x 2x 2x 2x 11

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 2 = 16

Therefore, the value for common factors is 16.

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 = 2649823585024/(1x16)

LCM = 2649823585024/16

LCM = 165613974064

Thus, we can understand that the LCM of 644,263,284,313,176 is 165613974064.
