Given numbers are 391,340,415,247

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

The LCM of 391,340,415,247 is 160317820.

Find LCM of 391,340,415,247 with Prime Factorization

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

5 x 17 x 23 x 4 x 83 x 247 = 160317820

Therefore, the lowest common multiple of 391,340,415,247 is 160317820.

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.

391 x 340 x 415 x 247 = 13627014700

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.

391 : 1, 17, 23, 391

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

415 : 1, 5, 83, 415

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,340,415,247, is 1.

Now, the common factors can be found like this.

391:17x 23

340:2x 2x 5x 17

415:5x 83

247:13x 19

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

5x 17 = 85

Therefore, the value for common factors is 85.

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 = 13627014700/(1x85)

LCM = 13627014700/85

LCM = 160317820

Thus, we can understand that the LCM of 391,340,415,247 is 160317820.
