Given numbers are 923,715,221,861

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

The LCM of 923,715,221,861 is 743047305.

Find LCM of 923,715,221,861 with Prime Factorization

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

13 x 71 x 55 x 17 x 861 = 743047305

Therefore, the lowest common multiple of 923,715,221,861 is 743047305.

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.

923 x 715 x 221 x 861 = 125574994545

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.

923 : 1, 13, 71, 923

715 : 1, 5, 11, 13, 55, 65, 143, 715

221 : 1, 13, 17, 221

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,715,221,861, is 1.

Now, the common factors can be found like this.

923:13x 71

715:5x 11x 13

221:13x 17

861:3x 7x 41

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 125574994545/(1x169)

LCM = 125574994545/169

LCM = 743047305

Thus, we can understand that the LCM of 923,715,221,861 is 743047305.
