Given numbers are 153,245,391,823

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

The LCM of 153,245,391,823 is 709553565.

Find LCM of 153,245,391,823 with Prime Factorization

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

17 x 9 x 245 x 23 x 823 = 709553565

Therefore, the lowest common multiple of 153,245,391,823 is 709553565.

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.

153 x 245 x 391 x 823 = 12062410605

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.

153 : 1, 3, 9, 17, 51, 153

245 : 1, 5, 7, 35, 49, 245

391 : 1, 17, 23, 391

823 : 1, 823

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,245,391,823, is 1.

Now, the common factors can be found like this.

153:3x 3x 17

245:5x 7x 7

391:17x 23

823:823

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

17 = 17

Therefore, the value for common factors is 17.

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 = 12062410605/(1x17)

LCM = 12062410605/17

LCM = 709553565

Thus, we can understand that the LCM of 153,245,391,823 is 709553565.
