Given numbers are 823,206,642,248

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

The LCM of 823,206,642,248 is 6748290552.

Find LCM of 823,206,642,248 with Prime Factorization

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

2 x 823 x 103 x 321 x 124 = 6748290552

Therefore, the lowest common multiple of 823,206,642,248 is 6748290552.

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 206 x 642 x 248 = 26993162208

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

206 : 1, 2, 103, 206

642 : 1, 2, 3, 6, 107, 214, 321, 642

248 : 1, 2, 4, 8, 31, 62, 124, 248

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,206,642,248, is 1.

Now, the common factors can be found like this.

823:823

206:2x 103

642:2x 3x 107

248:2x 2x 2x 31

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 = 26993162208/(1x4)

LCM = 26993162208/4

LCM = 6748290552

Thus, we can understand that the LCM of 823,206,642,248 is 6748290552.
