Given numbers are 644,523,428,508

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

The LCM of 644,523,428,508 is 4576938268.

Find LCM of 644,523,428,508 with Prime Factorization

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

2 x 2 x 161 x 523 x 107 x 127 = 4576938268

Therefore, the lowest common multiple of 644,523,428,508 is 4576938268.

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 523 x 428 x 508 = 73231012288

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

523 : 1, 523

428 : 1, 2, 4, 107, 214, 428

508 : 1, 2, 4, 127, 254, 508

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,523,428,508, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

523:523

428:2x 2x 107

508:2x 2x 127

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

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 73231012288/(1x16)

LCM = 73231012288/16

LCM = 4576938268

Thus, we can understand that the LCM of 644,523,428,508 is 4576938268.
