Given numbers are 688,772,408,888

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

The LCM of 688,772,408,888 is 250563408.

Find LCM of 688,772,408,888 with Prime Factorization

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

2 x 2 x 2 x 3 x 86 x 193 x 17 x 37 = 250563408

Therefore, the lowest common multiple of 688,772,408,888 is 250563408.

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.

688 x 772 x 408 x 888 = 192432697344

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

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

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,772,408,888, is 4.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

772:2x 2x 193

408:2x 2x 2x 3x 17

888:2x 2x 2x 3x 37

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 2x 2x 3 = 192

Therefore, the value for common factors is 192.

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 = 192432697344/(4x192)

LCM = 192432697344/768

LCM = 250563408

Thus, we can understand that the LCM of 688,772,408,888 is 250563408.
