Given numbers are 217,270,809,838,862

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

The LCM of 217,270,809,838,862 is 8559793993590.

Find LCM of 217,270,809,838,862 with Prime Factorization

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

2 x 217 x 135 x 809 x 419 x 431 = 8559793993590

Therefore, the lowest common multiple of 217,270,809,838,862 is 8559793993590.

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.

217 x 270 x 809 x 838 x 862 = 34239175974360

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.

217 : 1, 7, 31, 217

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

809 : 1, 809

838 : 1, 2, 419, 838

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,270,809,838,862, is 1.

Now, the common factors can be found like this.

217:7x 31

270:2x 3x 3x 3x 5

809:809

838:2x 419

862:2x 431

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 34239175974360/(1x4)

LCM = 34239175974360/4

LCM = 8559793993590

Thus, we can understand that the LCM of 217,270,809,838,862 is 8559793993590.
