Given numbers are 321,556,555,129,651

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

The LCM of 321,556,555,129,651 is 308091517860.

Find LCM of 321,556,555,129,651 with Prime Factorization

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

3 x 107 x 556 x 185 x 43 x 217 = 308091517860

Therefore, the lowest common multiple of 321,556,555,129,651 is 308091517860.

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.

321 x 556 x 555 x 129 x 651 = 8318470982220

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.

321 : 1, 3, 107, 321

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

555 : 1, 3, 5, 15, 37, 111, 185, 555

129 : 1, 3, 43, 129

651 : 1, 3, 7, 21, 31, 93, 217, 651

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,556,555,129,651, is 1.

Now, the common factors can be found like this.

321:3x 107

556:2x 2x 139

555:3x 5x 37

129:3x 43

651:3x 7x 31

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 8318470982220/(1x27)

LCM = 8318470982220/27

LCM = 308091517860

Thus, we can understand that the LCM of 321,556,555,129,651 is 308091517860.
