Given numbers are 644,460,552,163

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

The LCM of 644,460,552,163 is 3149160.

Find LCM of 644,460,552,163 with Prime Factorization

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

2 x 2 x 23 x 7 x 5 x 6 x 163 = 3149160

Therefore, the lowest common multiple of 644,460,552,163 is 3149160.

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.

644 x 460 x 552 x 163 = 26654490240

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,460,552,163, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

460:2x 2x 5x 23

552:2x 2x 2x 3x 23

163:163

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 2x 23x 23 = 8464

Therefore, the value for common factors is 8464.

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 = 26654490240/(1x8464)

LCM = 26654490240/8464

LCM = 3149160

Thus, we can understand that the LCM of 644,460,552,163 is 3149160.
