Given numbers are 247,324,156,431

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

The LCM of 247,324,156,431 is 34492068.

Find LCM of 247,324,156,431 with Prime Factorization

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

2 x 2 x 3 x 13 x 19 x 27 x 1 x 431 = 34492068

Therefore, the lowest common multiple of 247,324,156,431 is 34492068.

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 324 x 156 x 431 = 5380762608

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

324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,324,156,431, is 1.

Now, the common factors can be found like this.

247:13x 19

324:2x 2x 3x 3x 3x 3

156:2x 2x 3x 13

431:431

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 3x 13 = 156

Therefore, the value for common factors is 156.

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 = 5380762608/(1x156)

LCM = 5380762608/156

LCM = 34492068

Thus, we can understand that the LCM of 247,324,156,431 is 34492068.
