Given numbers are 1,329,991,455

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

The LCM of 1,329,991,455 is 21192535.

Find LCM of 1,329,991,455 with Prime Factorization

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

7 x 1 x 47 x 991 x 65 = 21192535

Therefore, the lowest common multiple of 1,329,991,455 is 21192535.

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.

1 x 329 x 991 x 455 = 148347745

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.

1 : 1

329 : 1, 7, 47, 329

991 : 1, 991

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,329,991,455, is 1.

Now, the common factors can be found like this.

1:

329:7x 47

991:991

455:5x 7x 13

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

7 = 7

Therefore, the value for common factors is 7.

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 = 148347745/(1x7)

LCM = 148347745/7

LCM = 21192535

Thus, we can understand that the LCM of 1,329,991,455 is 21192535.
