Given numbers are 163,871,406,784

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

The LCM of 163,871,406,784 is 3227898128.

Find LCM of 163,871,406,784 with Prime Factorization

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

2 x 7 x 163 x 871 x 29 x 56 = 3227898128

Therefore, the lowest common multiple of 163,871,406,784 is 3227898128.

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.

163 x 871 x 406 x 784 = 45190573792

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.

163 : 1, 163

871 : 1, 13, 67, 871

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

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,871,406,784, is 1.

Now, the common factors can be found like this.

163:163

871:13x 67

406:2x 7x 29

784:2x 2x 2x 2x 7x 7

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 45190573792/(1x14)

LCM = 45190573792/14

LCM = 3227898128

Thus, we can understand that the LCM of 163,871,406,784 is 3227898128.
