Given numbers are 355,245,721,485

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

The LCM of 355,245,721,485 is 173793445.

Find LCM of 355,245,721,485 with Prime Factorization

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

5 x 7 x 71 x 7 x 103 x 97 = 173793445

Therefore, the lowest common multiple of 355,245,721,485 is 173793445.

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.

355 x 245 x 721 x 485 = 30413852875

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.

355 : 1, 5, 71, 355

245 : 1, 5, 7, 35, 49, 245

721 : 1, 7, 103, 721

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,245,721,485, is 1.

Now, the common factors can be found like this.

355:5x 71

245:5x 7x 7

721:7x 103

485:5x 97

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

5x 5x 7 = 175

Therefore, the value for common factors is 175.

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 = 30413852875/(1x175)

LCM = 30413852875/175

LCM = 173793445

Thus, we can understand that the LCM of 355,245,721,485 is 173793445.
