Given numbers are 644,515,206,523

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

The LCM of 644,515,206,523 is 173458180.

Find LCM of 644,515,206,523 with Prime Factorization

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

2 x 103 x 322 x 5 x 1 x 523 = 173458180

Therefore, the lowest common multiple of 644,515,206,523 is 173458180.

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 515 x 206 x 523 = 35732385080

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

515 : 1, 5, 103, 515

206 : 1, 2, 103, 206

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,515,206,523, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

515:5x 103

206:2x 103

523:523

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 35732385080/(1x206)

LCM = 35732385080/206

LCM = 173458180

Thus, we can understand that the LCM of 644,515,206,523 is 173458180.
