Given numbers are 857,871,181,543

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

The LCM of 857,871,181,543 is 405320721.

Find LCM of 857,871,181,543 with Prime Factorization

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

181 x 857 x 871 x 1 x 3 = 405320721

Therefore, the lowest common multiple of 857,871,181,543 is 405320721.

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 871 x 181 x 543 = 73363050501

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

871 : 1, 13, 67, 871

181 : 1, 181

543 : 1, 3, 181, 543

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,871,181,543, is 1.

Now, the common factors can be found like this.

857:857

871:13x 67

181:181

543:3x 181

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

181 = 181

Therefore, the value for common factors is 181.

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 = 73363050501/(1x181)

LCM = 73363050501/181

LCM = 405320721

Thus, we can understand that the LCM of 857,871,181,543 is 405320721.
