Given numbers are 422,558,403,487

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

The LCM of 422,558,403,487 is 745399278.

Find LCM of 422,558,403,487 with Prime Factorization

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

2 x 31 x 211 x 9 x 13 x 487 = 745399278

Therefore, the lowest common multiple of 422,558,403,487 is 745399278.

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.

422 x 558 x 403 x 487 = 46214755236

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.

422 : 1, 2, 211, 422

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

403 : 1, 13, 31, 403

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,558,403,487, is 1.

Now, the common factors can be found like this.

422:2x 211

558:2x 3x 3x 31

403:13x 31

487:487

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

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 46214755236/(1x62)

LCM = 46214755236/62

LCM = 745399278

Thus, we can understand that the LCM of 422,558,403,487 is 745399278.
