Given numbers are 270,399,391,698

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

The LCM of 270,399,391,698 is 4900242690.

Find LCM of 270,399,391,698 with Prime Factorization

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

2 x 3 x 45 x 133 x 391 x 349 = 4900242690

Therefore, the lowest common multiple of 270,399,391,698 is 4900242690.

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.

270 x 399 x 391 x 698 = 29401456140

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.

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

399 : 1, 3, 7, 19, 21, 57, 133, 399

391 : 1, 17, 23, 391

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,399,391,698, is 1.

Now, the common factors can be found like this.

270:2x 3x 3x 3x 5

399:3x 7x 19

391:17x 23

698:2x 349

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 = 29401456140/(1x6)

LCM = 29401456140/6

LCM = 4900242690

Thus, we can understand that the LCM of 270,399,391,698 is 4900242690.
