Given numbers are 423,381,126,857

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

The LCM of 423,381,126,857 is 644544558.

Find LCM of 423,381,126,857 with Prime Factorization

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

3 x 3 x 47 x 127 x 14 x 857 = 644544558

Therefore, the lowest common multiple of 423,381,126,857 is 644544558.

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.

423 x 381 x 126 x 857 = 17402703066

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.

423 : 1, 3, 9, 47, 141, 423

381 : 1, 3, 127, 381

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,381,126,857, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

381:3x 127

126:2x 3x 3x 7

857:857

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 17402703066/(1x27)

LCM = 17402703066/27

LCM = 644544558

Thus, we can understand that the LCM of 423,381,126,857 is 644544558.
