Given numbers are 644,998,325,538

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

The LCM of 644,998,325,538 is 28094548300.

Find LCM of 644,998,325,538 with Prime Factorization

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

2 x 322 x 499 x 325 x 269 = 28094548300

Therefore, the lowest common multiple of 644,998,325,538 is 28094548300.

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.

644 x 998 x 325 x 538 = 112378193200

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

998 : 1, 2, 499, 998

325 : 1, 5, 13, 25, 65, 325

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,998,325,538, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

998:2x 499

325:5x 5x 13

538:2x 269

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 = 112378193200/(1x4)

LCM = 112378193200/4

LCM = 28094548300

Thus, we can understand that the LCM of 644,998,325,538 is 28094548300.
