Given numbers are 791,857,406,742

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

The LCM of 791,857,406,742 is 2083824638.

Find LCM of 791,857,406,742 with Prime Factorization

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

2 x 7 x 113 x 857 x 29 x 53 = 2083824638

Therefore, the lowest common multiple of 791,857,406,742 is 2083824638.

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 857 x 406 x 742 = 204214814524

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

857 : 1, 857

406 : 1, 2, 7, 14, 29, 58, 203, 406

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,857,406,742, is 1.

Now, the common factors can be found like this.

791:7x 113

857:857

406:2x 7x 29

742:2x 7x 53

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 204214814524/(1x98)

LCM = 204214814524/98

LCM = 2083824638

Thus, we can understand that the LCM of 791,857,406,742 is 2083824638.
