Given numbers are 556,842,287,407

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

The LCM of 556,842,287,407 is 27342183484.

Find LCM of 556,842,287,407 with Prime Factorization

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

2 x 278 x 421 x 287 x 407 = 27342183484

Therefore, the lowest common multiple of 556,842,287,407 is 27342183484.

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.

556 x 842 x 287 x 407 = 54684366968

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.

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

842 : 1, 2, 421, 842

287 : 1, 7, 41, 287

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,842,287,407, is 1.

Now, the common factors can be found like this.

556:2x 2x 139

842:2x 421

287:7x 41

407:11x 37

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

2 = 2

Therefore, the value for common factors is 2.

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 = 54684366968/(1x2)

LCM = 54684366968/2

LCM = 27342183484

Thus, we can understand that the LCM of 556,842,287,407 is 27342183484.
