Given numbers are 645,522,497

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

The LCM of 645,522,497 is 55778310.

Find LCM of 645,522,497 with Prime Factorization

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

3 x 215 x 174 x 497 = 55778310

Therefore, the lowest common multiple of 645,522,497 is 55778310.

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.

645 x 522 x 497 = 167334930

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,522,497, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

522:2x 3x 3x 29

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.

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 = 167334930/(1x3)

LCM = 167334930/3

LCM = 55778310

Thus, we can understand that the LCM of 645,522,497 is 55778310.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 526, 518, 876
