Given numbers are 247,454,418,512,163

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

The LCM of 247,454,418,512,163 is 51472239104.

Find LCM of 247,454,418,512,163 with Prime Factorization

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

2 x 19 x 13 x 227 x 11 x 256 x 163 = 51472239104

Therefore, the lowest common multiple of 247,454,418,512,163 is 51472239104.

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 454 x 418 x 512 x 163 = 3911890171904

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

454 : 1, 2, 227, 454

418 : 1, 2, 11, 19, 22, 38, 209, 418

512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,454,418,512,163, is 1.

Now, the common factors can be found like this.

247:13x 19

454:2x 227

418:2x 11x 19

512:2x 2x 2x 2x 2x 2x 2x 2x 2

163:163

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 19 = 76

Therefore, the value for common factors is 76.

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 = 3911890171904/(1x76)

LCM = 3911890171904/76

LCM = 51472239104

Thus, we can understand that the LCM of 247,454,418,512,163 is 51472239104.
