Given numbers are 291,576,216,621

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

The LCM of 291,576,216,621 is 3855168.

Find LCM of 291,576,216,621 with Prime Factorization

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

2 x 2 x 2 x 3 x 3 x 3 x 97 x 8 x 1 x 23 = 3855168

Therefore, the lowest common multiple of 291,576,216,621 is 3855168.

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 576 x 216 x 621 = 22483339776

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

576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

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

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,576,216,621, is 3.

Now, the common factors can be found like this.

291:3x 97

576:2x 2x 2x 2x 2x 2x 3x 3

216:2x 2x 2x 3x 3x 3

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.

2x 2x 2x 3x 3x 3x 3x 3 = 1944

Therefore, the value for common factors is 1944.

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 = 22483339776/(3x1944)

LCM = 22483339776/5832

LCM = 3855168

Thus, we can understand that the LCM of 291,576,216,621 is 3855168.
