Given numbers are 421,268,871,486

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

The LCM of 421,268,871,486 is 356423652.

Find LCM of 421,268,871,486 with Prime Factorization

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

2 x 67 x 421 x 2 x 13 x 243 = 356423652

Therefore, the lowest common multiple of 421,268,871,486 is 356423652.

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.

421 x 268 x 871 x 486 = 47760769368

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.

421 : 1, 421

268 : 1, 2, 4, 67, 134, 268

871 : 1, 13, 67, 871

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,268,871,486, is 1.

Now, the common factors can be found like this.

421:421

268:2x 2x 67

871:13x 67

486:2x 3x 3x 3x 3x 3

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 = 47760769368/(1x134)

LCM = 47760769368/134

LCM = 356423652

Thus, we can understand that the LCM of 421,268,871,486 is 356423652.
