Given numbers are 221,402,488,747,813

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

The LCM of 221,402,488,747,813 is 1462772513592.

Find LCM of 221,402,488,747,813 with Prime Factorization

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

2 x 3 x 221 x 67 x 244 x 249 x 271 = 1462772513592

Therefore, the lowest common multiple of 221,402,488,747,813 is 1462772513592.

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.

221 x 402 x 488 x 747 x 813 = 26329905244656

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.

221 : 1, 13, 17, 221

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

488 : 1, 2, 4, 8, 61, 122, 244, 488

747 : 1, 3, 9, 83, 249, 747

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,402,488,747,813, is 1.

Now, the common factors can be found like this.

221:13x 17

402:2x 3x 67

488:2x 2x 2x 61

747:3x 3x 83

813:3x 271

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 26329905244656/(1x18)

LCM = 26329905244656/18

LCM = 1462772513592

Thus, we can understand that the LCM of 221,402,488,747,813 is 1462772513592.
