Given numbers are 291,917,403,621

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

The LCM of 291,917,403,621 is 22260643587.

Find LCM of 291,917,403,621 with Prime Factorization

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

3 x 97 x 917 x 403 x 207 = 22260643587

Therefore, the lowest common multiple of 291,917,403,621 is 22260643587.

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.

291 x 917 x 403 x 621 = 66781930761

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.

291 : 1, 3, 97, 291

917 : 1, 7, 131, 917

403 : 1, 13, 31, 403

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 291,917,403,621, is 1.

Now, the common factors can be found like this.

291:3x 97

917:7x 131

403:13x 31

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 = 66781930761/(1x3)

LCM = 66781930761/3

LCM = 22260643587

Thus, we can understand that the LCM of 291,917,403,621 is 22260643587.
