Given numbers are 247,247,613,447

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

The LCM of 247,247,613,447 is 67680717.

Find LCM of 247,247,613,447 with Prime Factorization

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

13 x 19 x 1 x 1 x 613 x 447 = 67680717

Therefore, the lowest common multiple of 247,247,613,447 is 67680717.

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.

247 x 247 x 613 x 447 = 16717137099

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.

247 : 1, 13, 19, 247

247 : 1, 13, 19, 247

613 : 1, 613

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,247,613,447, is 1.

Now, the common factors can be found like this.

247:13x 19

247:13x 19

613:613

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.

13x 19 = 247

Therefore, the value for common factors is 247.

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 = 16717137099/(1x247)

LCM = 16717137099/247

LCM = 67680717

Thus, we can understand that the LCM of 247,247,613,447 is 67680717.
