Given numbers are 393,857,769,786

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

The LCM of 393,857,769,786 is 517999938.

Find LCM of 393,857,769,786 with Prime Factorization

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

3 x 131 x 1 x 857 x 769 x 2 = 517999938

Therefore, the lowest common multiple of 393,857,769,786 is 517999938.

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.

393 x 857 x 769 x 786 = 203573975634

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.

393 : 1, 3, 131, 393

857 : 1, 857

769 : 1, 769

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,857,769,786, is 1.

Now, the common factors can be found like this.

393:3x 131

857:857

769:769

786:2x 3x 131

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

3x 131 = 393

Therefore, the value for common factors is 393.

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 = 203573975634/(1x393)

LCM = 203573975634/393

LCM = 517999938

Thus, we can understand that the LCM of 393,857,769,786 is 517999938.
