Given numbers are 821,871,402,404

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

The LCM of 821,871,402,404 is 866690292.

Find LCM of 821,871,402,404 with Prime Factorization

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

2 x 67 x 821 x 13 x 3 x 202 = 866690292

Therefore, the lowest common multiple of 821,871,402,404 is 866690292.

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.

821 x 871 x 402 x 404 = 116136499128

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.

821 : 1, 821

871 : 1, 13, 67, 871

402 : 1, 2, 3, 6, 67, 134, 201, 402

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,871,402,404, is 1.

Now, the common factors can be found like this.

821:821

871:13x 67

402:2x 3x 67

404:2x 2x 101

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

2x 67 = 134

Therefore, the value for common factors is 134.

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 = 116136499128/(1x134)

LCM = 116136499128/134

LCM = 866690292

Thus, we can understand that the LCM of 821,871,402,404 is 866690292.
