Given numbers are 689,126,447,447

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

The LCM of 689,126,447,447 is 12935286.

Find LCM of 689,126,447,447 with Prime Factorization

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

3 x 149 x 689 x 42 x 1 x 1 = 12935286

Therefore, the lowest common multiple of 689,126,447,447 is 12935286.

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.

689 x 126 x 447 x 447 = 17346218526

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.

689 : 1, 13, 53, 689

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

447 : 1, 3, 149, 447

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,126,447,447, is 1.

Now, the common factors can be found like this.

689:13x 53

126:2x 3x 3x 7

447:3x 149

447:3x 149

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 149 = 1341

Therefore, the value for common factors is 1341.

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 = 17346218526/(1x1341)

LCM = 17346218526/1341

LCM = 12935286

Thus, we can understand that the LCM of 689,126,447,447 is 12935286.
