Given numbers are 823,221,197,286

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

The LCM of 823,221,197,286 is 788280922.

Find LCM of 823,221,197,286 with Prime Factorization

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

13 x 823 x 17 x 197 x 22 = 788280922

Therefore, the lowest common multiple of 823,221,197,286 is 788280922.

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.

823 x 221 x 197 x 286 = 10247651986

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.

823 : 1, 823

221 : 1, 13, 17, 221

197 : 1, 197

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,221,197,286, is 1.

Now, the common factors can be found like this.

823:823

221:13x 17

197:197

286:2x 11x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 10247651986/(1x13)

LCM = 10247651986/13

LCM = 788280922

Thus, we can understand that the LCM of 823,221,197,286 is 788280922.
