Given numbers are 170,991,629,505

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

The LCM of 170,991,629,505 is 629572390.

Find LCM of 170,991,629,505 with Prime Factorization

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

5 x 17 x 2 x 991 x 37 x 101 = 629572390

Therefore, the lowest common multiple of 170,991,629,505 is 629572390.

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.

170 x 991 x 629 x 505 = 53513653150

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.

170 : 1, 2, 5, 10, 17, 34, 85, 170

991 : 1, 991

629 : 1, 17, 37, 629

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,991,629,505, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

991:991

629:17x 37

505:5x 101

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

5x 17 = 85

Therefore, the value for common factors is 85.

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 = 53513653150/(1x85)

LCM = 53513653150/85

LCM = 629572390

Thus, we can understand that the LCM of 170,991,629,505 is 629572390.
