Given numbers are 643,428,325,497,497

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

The LCM of 643,428,325,497,497 is 44452326100.

Find LCM of 643,428,325,497,497 with Prime Factorization

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

7 x 71 x 643 x 428 x 325 x 1 x 1 = 44452326100

Therefore, the lowest common multiple of 643,428,325,497,497 is 44452326100.

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.

643 x 428 x 325 x 497 x 497 = 22092806071700

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.

643 : 1, 643

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

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

497 : 1, 7, 71, 497

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,428,325,497,497, is 1.

Now, the common factors can be found like this.

643:643

428:2x 2x 107

325:5x 5x 13

497:7x 71

497:7x 71

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

7x 71 = 497

Therefore, the value for common factors is 497.

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 = 22092806071700/(1x497)

LCM = 22092806071700/497

LCM = 44452326100

Thus, we can understand that the LCM of 643,428,325,497,497 is 44452326100.
