Given numbers are 391,791,786,791

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

The LCM of 391,791,786,791 is 243094866.

Find LCM of 391,791,786,791 with Prime Factorization

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

7 x 113 x 391 x 1 x 786 x 1 = 243094866

Therefore, the lowest common multiple of 391,791,786,791 is 243094866.

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.

391 x 791 x 786 x 791 = 192288039006

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.

391 : 1, 17, 23, 391

791 : 1, 7, 113, 791

786 : 1, 2, 3, 6, 131, 262, 393, 786

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,791,786,791, is 1.

Now, the common factors can be found like this.

391:17x 23

791:7x 113

786:2x 3x 131

791:7x 113

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

7x 113 = 791

Therefore, the value for common factors is 791.

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 = 192288039006/(1x791)

LCM = 192288039006/791

LCM = 243094866

Thus, we can understand that the LCM of 391,791,786,791 is 243094866.
