Given numbers are 642,556,869,358

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

The LCM of 642,556,869,358 is 27762120276.

Find LCM of 642,556,869,358 with Prime Factorization

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

2 x 321 x 278 x 869 x 179 = 27762120276

Therefore, the lowest common multiple of 642,556,869,358 is 27762120276.

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.

642 x 556 x 869 x 358 = 111048481104

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.

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

556 : 1, 2, 4, 139, 278, 556

869 : 1, 11, 79, 869

358 : 1, 2, 179, 358

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,556,869,358, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

556:2x 2x 139

869:11x 79

358:2x 179

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 111048481104/(1x4)

LCM = 111048481104/4

LCM = 27762120276

Thus, we can understand that the LCM of 642,556,869,358 is 27762120276.
