Given numbers are 823,418,646,647,152

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

The LCM of 823,418,646,647,152 is 15135239944.

Find LCM of 823,418,646,647,152 with Prime Factorization

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

2 x 19 x 823 x 11 x 17 x 647 x 4 = 15135239944

Therefore, the lowest common multiple of 823,418,646,647,152 is 15135239944.

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 418 x 646 x 647 x 152 = 21855286479136

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

418 : 1, 2, 11, 19, 22, 38, 209, 418

646 : 1, 2, 17, 19, 34, 38, 323, 646

647 : 1, 647

152 : 1, 2, 4, 8, 19, 38, 76, 152

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,418,646,647,152, is 1.

Now, the common factors can be found like this.

823:823

418:2x 11x 19

646:2x 17x 19

647:647

152:2x 2x 2x 19

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 19x 19 = 1444

Therefore, the value for common factors is 1444.

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 = 21855286479136/(1x1444)

LCM = 21855286479136/1444

LCM = 15135239944

Thus, we can understand that the LCM of 823,418,646,647,152 is 15135239944.
