Given numbers are 247,201,685,455

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

The LCM of 247,201,685,455 is 238057365.

Find LCM of 247,201,685,455 with Prime Factorization

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

5 x 13 x 19 x 201 x 137 x 7 = 238057365

Therefore, the lowest common multiple of 247,201,685,455 is 238057365.

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 201 x 685 x 455 = 15473728725

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

201 : 1, 3, 67, 201

685 : 1, 5, 137, 685

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,201,685,455, is 1.

Now, the common factors can be found like this.

247:13x 19

201:3x 67

685:5x 137

455:5x 7x 13

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

5x 13 = 65

Therefore, the value for common factors is 65.

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 = 15473728725/(1x65)

LCM = 15473728725/65

LCM = 238057365

Thus, we can understand that the LCM of 247,201,685,455 is 238057365.
