Given numbers are 399,821,668,524

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

The LCM of 399,821,668,524 is 28665783132.

Find LCM of 399,821,668,524 with Prime Factorization

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

2 x 2 x 399 x 821 x 167 x 131 = 28665783132

Therefore, the lowest common multiple of 399,821,668,524 is 28665783132.

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.

399 x 821 x 668 x 524 = 114663132528

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.

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

821 : 1, 821

668 : 1, 2, 4, 167, 334, 668

524 : 1, 2, 4, 131, 262, 524

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,821,668,524, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

821:821

668:2x 2x 167

524:2x 2x 131

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 = 114663132528/(1x4)

LCM = 114663132528/4

LCM = 28665783132

Thus, we can understand that the LCM of 399,821,668,524 is 28665783132.
