Given numbers are 791,689,715,806

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

The LCM of 791,689,715,806 is 1858446590.

Find LCM of 791,689,715,806 with Prime Factorization

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

13 x 791 x 53 x 55 x 62 = 1858446590

Therefore, the lowest common multiple of 791,689,715,806 is 1858446590.

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.

791 x 689 x 715 x 806 = 314077473710

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.

791 : 1, 7, 113, 791

689 : 1, 13, 53, 689

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

806 : 1, 2, 13, 26, 31, 62, 403, 806

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,689,715,806, is 1.

Now, the common factors can be found like this.

791:7x 113

689:13x 53

715:5x 11x 13

806:2x 13x 31

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 = 314077473710/(1x169)

LCM = 314077473710/169

LCM = 1858446590

Thus, we can understand that the LCM of 791,689,715,806 is 1858446590.
