Given numbers are 814,987,521,621

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

The LCM of 814,987,521,621 is 86646221046.

Find LCM of 814,987,521,621 with Prime Factorization

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

3 x 814 x 329 x 521 x 207 = 86646221046

Therefore, the lowest common multiple of 814,987,521,621 is 86646221046.

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.

814 x 987 x 521 x 621 = 259938663138

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.

814 : 1, 2, 11, 22, 37, 74, 407, 814

987 : 1, 3, 7, 21, 47, 141, 329, 987

521 : 1, 521

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,987,521,621, is 1.

Now, the common factors can be found like this.

814:2x 11x 37

987:3x 7x 47

521:521

621:3x 3x 3x 23

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

3 = 3

Therefore, the value for common factors is 3.

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 = 259938663138/(1x3)

LCM = 259938663138/3

LCM = 86646221046

Thus, we can understand that the LCM of 814,987,521,621 is 86646221046.
