Given numbers are 399,647,602,284

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

The LCM of 399,647,602,284 is 3152564436.

Find LCM of 399,647,602,284 with Prime Factorization

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

2 x 7 x 57 x 647 x 43 x 142 = 3152564436

Therefore, the lowest common multiple of 399,647,602,284 is 3152564436.

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 647 x 602 x 284 = 44135902104

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

647 : 1, 647

602 : 1, 2, 7, 14, 43, 86, 301, 602

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,647,602,284, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

647:647

602:2x 7x 43

284:2x 2x 71

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 44135902104/(1x14)

LCM = 44135902104/14

LCM = 3152564436

Thus, we can understand that the LCM of 399,647,602,284 is 3152564436.
