Given numbers are 261,395,642,878

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

The LCM of 261,395,642,878 is 9685362870.

Find LCM of 261,395,642,878 with Prime Factorization

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

2 x 3 x 87 x 395 x 107 x 439 = 9685362870

Therefore, the lowest common multiple of 261,395,642,878 is 9685362870.

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.

261 x 395 x 642 x 878 = 58112177220

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.

261 : 1, 3, 9, 29, 87, 261

395 : 1, 5, 79, 395

642 : 1, 2, 3, 6, 107, 214, 321, 642

878 : 1, 2, 439, 878

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,395,642,878, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

395:5x 79

642:2x 3x 107

878:2x 439

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 = 58112177220/(1x6)

LCM = 58112177220/6

LCM = 9685362870

Thus, we can understand that the LCM of 261,395,642,878 is 9685362870.
