Given numbers are 428,208,647,848

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

The LCM of 428,208,647,848 is 763180496.

Find LCM of 428,208,647,848 with Prime Factorization

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

2 x 2 x 2 x 2 x 107 x 13 x 647 x 53 = 763180496

Therefore, the lowest common multiple of 428,208,647,848 is 763180496.

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.

428 x 208 x 647 x 848 = 48843551744

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.

428 : 1, 2, 4, 107, 214, 428

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

647 : 1, 647

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,208,647,848, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

208:2x 2x 2x 2x 13

647:647

848:2x 2x 2x 2x 53

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 2 = 64

Therefore, the value for common factors is 64.

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 = 48843551744/(1x64)

LCM = 48843551744/64

LCM = 763180496

Thus, we can understand that the LCM of 428,208,647,848 is 763180496.
