Given numbers are 863,520,209,208

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

The LCM of 863,520,209,208 is 187581680.

Find LCM of 863,520,209,208 with Prime Factorization

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

2 x 2 x 2 x 13 x 863 x 5 x 209 x 2 = 187581680

Therefore, the lowest common multiple of 863,520,209,208 is 187581680.

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.

863 x 520 x 209 x 208 = 19508494720

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.

863 : 1, 863

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

209 : 1, 11, 19, 209

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,520,209,208, is 1.

Now, the common factors can be found like this.

863:863

520:2x 2x 2x 5x 13

209:11x 19

208:2x 2x 2x 2x 13

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 13 = 104

Therefore, the value for common factors is 104.

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 = 19508494720/(1x104)

LCM = 19508494720/104

LCM = 187581680

Thus, we can understand that the LCM of 863,520,209,208 is 187581680.
