Given numbers are 857,667,345,406

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

The LCM of 857,667,345,406 is 120039990.

Find LCM of 857,667,345,406 with Prime Factorization

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

23 x 29 x 857 x 1 x 15 x 14 = 120039990

Therefore, the lowest common multiple of 857,667,345,406 is 120039990.

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.

857 x 667 x 345 x 406 = 80066673330

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.

857 : 1, 857

667 : 1, 23, 29, 667

345 : 1, 3, 5, 15, 23, 69, 115, 345

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,667,345,406, is 1.

Now, the common factors can be found like this.

857:857

667:23x 29

345:3x 5x 23

406:2x 7x 29

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

23x 29 = 667

Therefore, the value for common factors is 667.

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 = 80066673330/(1x667)

LCM = 80066673330/667

LCM = 120039990

Thus, we can understand that the LCM of 857,667,345,406 is 120039990.
