Given numbers are 647,207,303,521

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

The LCM of 647,207,303,521 is 7047477909.

Find LCM of 647,207,303,521 with Prime Factorization

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

3 x 647 x 69 x 101 x 521 = 7047477909

Therefore, the lowest common multiple of 647,207,303,521 is 7047477909.

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.

647 x 207 x 303 x 521 = 21142433727

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.

647 : 1, 647

207 : 1, 3, 9, 23, 69, 207

303 : 1, 3, 101, 303

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,207,303,521, is 1.

Now, the common factors can be found like this.

647:647

207:3x 3x 23

303:3x 101

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 = 21142433727/(1x3)

LCM = 21142433727/3

LCM = 7047477909

Thus, we can understand that the LCM of 647,207,303,521 is 7047477909.
