Given numbers are 709,531,391,969

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

The LCM of 709,531,391,969 is 2796862491.

Find LCM of 709,531,391,969 with Prime Factorization

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

3 x 17 x 709 x 177 x 23 x 19 = 2796862491

Therefore, the lowest common multiple of 709,531,391,969 is 2796862491.

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.

709 x 531 x 391 x 969 = 142639987041

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.

709 : 1, 709

531 : 1, 3, 9, 59, 177, 531

391 : 1, 17, 23, 391

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,531,391,969, is 1.

Now, the common factors can be found like this.

709:709

531:3x 3x 59

391:17x 23

969:3x 17x 19

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

3x 17 = 51

Therefore, the value for common factors is 51.

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 = 142639987041/(1x51)

LCM = 142639987041/51

LCM = 2796862491

Thus, we can understand that the LCM of 709,531,391,969 is 2796862491.
