Given numbers are 3,987,573,321

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

The LCM of 3,987,573,321 is 20171319.

Find LCM of 3,987,573,321 with Prime Factorization

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

3 x 1 x 329 x 191 x 107 = 20171319

Therefore, the lowest common multiple of 3,987,573,321 is 20171319.

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.

3 x 987 x 573 x 321 = 544625613

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.

3 : 1, 3

987 : 1, 3, 7, 21, 47, 141, 329, 987

573 : 1, 3, 191, 573

321 : 1, 3, 107, 321

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,987,573,321, is 3.

Now, the common factors can be found like this.

3:3

987:3x 7x 47

573:3x 191

321:3x 107

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 544625613/(3x9)

LCM = 544625613/27

LCM = 20171319

Thus, we can understand that the LCM of 3,987,573,321 is 20171319.
