Given numbers are 285,176,649,671,871

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

The LCM of 285,176,649,671,871 is 157238006640.

Find LCM of 285,176,649,671,871 with Prime Factorization

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

11 x 285 x 16 x 59 x 61 x 871 = 157238006640

Therefore, the lowest common multiple of 285,176,649,671,871 is 157238006640.

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.

285 x 176 x 649 x 671 x 871 = 19025798803440

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

649 : 1, 11, 59, 649

671 : 1, 11, 61, 671

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,176,649,671,871, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

176:2x 2x 2x 2x 11

649:11x 59

671:11x 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.

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 19025798803440/(1x121)

LCM = 19025798803440/121

LCM = 157238006640

Thus, we can understand that the LCM of 285,176,649,671,871 is 157238006640.
