Given numbers are 681,272,424,669

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

The LCM of 681,272,424,669 is 2189257008.

Find LCM of 681,272,424,669 with Prime Factorization

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

2 x 2 x 2 x 3 x 227 x 34 x 53 x 223 = 2189257008

Therefore, the lowest common multiple of 681,272,424,669 is 2189257008.

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.

681 x 272 x 424 x 669 = 52542168192

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.

681 : 1, 3, 227, 681

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

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

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,272,424,669, is 1.

Now, the common factors can be found like this.

681:3x 227

272:2x 2x 2x 2x 17

424:2x 2x 2x 53

669:3x 223

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 3 = 24

Therefore, the value for common factors is 24.

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 = 52542168192/(1x24)

LCM = 52542168192/24

LCM = 2189257008

Thus, we can understand that the LCM of 681,272,424,669 is 2189257008.
