Given numbers are 817,122,122,871

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

The LCM of 817,122,122,871 is 86816054.

Find LCM of 817,122,122,871 with Prime Factorization

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

2 x 61 x 817 x 1 x 1 x 871 = 86816054

Therefore, the lowest common multiple of 817,122,122,871 is 86816054.

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.

817 x 122 x 122 x 871 = 10591558588

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.

817 : 1, 19, 43, 817

122 : 1, 2, 61, 122

122 : 1, 2, 61, 122

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,122,122,871, is 1.

Now, the common factors can be found like this.

817:19x 43

122:2x 61

122:2x 61

871:13x 67

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

2x 61 = 122

Therefore, the value for common factors is 122.

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 = 10591558588/(1x122)

LCM = 10591558588/122

LCM = 86816054

Thus, we can understand that the LCM of 817,122,122,871 is 86816054.
