Given numbers are 843,432,974,391

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

The LCM of 843,432,974,391 is 23115100464.

Find LCM of 843,432,974,391 with Prime Factorization

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

2 x 3 x 281 x 72 x 487 x 391 = 23115100464

Therefore, the lowest common multiple of 843,432,974,391 is 23115100464.

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.

843 x 432 x 974 x 391 = 138690602784

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.

843 : 1, 3, 281, 843

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

974 : 1, 2, 487, 974

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,432,974,391, is 1.

Now, the common factors can be found like this.

843:3x 281

432:2x 2x 2x 2x 3x 3x 3

974:2x 487

391:17x 23

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 138690602784/(1x6)

LCM = 138690602784/6

LCM = 23115100464

Thus, we can understand that the LCM of 843,432,974,391 is 23115100464.
