Given numbers are 644,753,639,521

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

The LCM of 644,753,639,521 is 53814358836.

Find LCM of 644,753,639,521 with Prime Factorization

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

3 x 644 x 251 x 213 x 521 = 53814358836

Therefore, the lowest common multiple of 644,753,639,521 is 53814358836.

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 753 x 639 x 521 = 161443076508

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

753 : 1, 3, 251, 753

639 : 1, 3, 9, 71, 213, 639

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,753,639,521, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

753:3x 251

639:3x 3x 71

521:521

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

3 = 3

Therefore, the value for common factors is 3.

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 = 161443076508/(1x3)

LCM = 161443076508/3

LCM = 53814358836

Thus, we can understand that the LCM of 644,753,639,521 is 53814358836.
