Given numbers are 871,778,104,221

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

The LCM of 871,778,104,221 is 46079384.

Find LCM of 871,778,104,221 with Prime Factorization

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

2 x 13 x 67 x 389 x 4 x 17 = 46079384

Therefore, the lowest common multiple of 871,778,104,221 is 46079384.

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.

871 x 778 x 104 x 221 = 15574831792

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.

871 : 1, 13, 67, 871

778 : 1, 2, 389, 778

104 : 1, 2, 4, 8, 13, 26, 52, 104

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,778,104,221, is 1.

Now, the common factors can be found like this.

871:13x 67

778:2x 389

104:2x 2x 2x 13

221:13x 17

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

2x 13x 13 = 338

Therefore, the value for common factors is 338.

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 = 15574831792/(1x338)

LCM = 15574831792/338

LCM = 46079384

Thus, we can understand that the LCM of 871,778,104,221 is 46079384.
