Given numbers are 216,643,772,641

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

The LCM of 216,643,772,641 is 17182251144.

Find LCM of 216,643,772,641 with Prime Factorization

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

2 x 2 x 54 x 643 x 193 x 641 = 17182251144

Therefore, the lowest common multiple of 216,643,772,641 is 17182251144.

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.

216 x 643 x 772 x 641 = 68729004576

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.

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

643 : 1, 643

772 : 1, 2, 4, 193, 386, 772

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,643,772,641, is 1.

Now, the common factors can be found like this.

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

643:643

772:2x 2x 193

641:641

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 = 68729004576/(1x4)

LCM = 68729004576/4

LCM = 17182251144

Thus, we can understand that the LCM of 216,643,772,641 is 17182251144.
