Given numbers are 692,691,289,18

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

The LCM of 692,691,289,18 is 1243725372.

Find LCM of 692,691,289,18 with Prime Factorization

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

2 x 346 x 691 x 289 x 9 = 1243725372

Therefore, the lowest common multiple of 692,691,289,18 is 1243725372.

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.

692 x 691 x 289 x 18 = 2487450744

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.

692 : 1, 2, 4, 173, 346, 692

691 : 1, 691

289 : 1, 17, 289

18 : 1, 2, 3, 6, 9, 18

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,691,289,18, is 1.

Now, the common factors can be found like this.

692:2x 2x 173

691:691

289:17x 17

18:2x 3x 3

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

2 = 2

Therefore, the value for common factors is 2.

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 = 2487450744/(1x2)

LCM = 2487450744/2

LCM = 1243725372

Thus, we can understand that the LCM of 692,691,289,18 is 1243725372.
