Given numbers are 486,691,393,393

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

The LCM of 486,691,393,393 is 43993206.

Find LCM of 486,691,393,393 with Prime Factorization

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

3 x 131 x 162 x 691 x 1 x 1 = 43993206

Therefore, the lowest common multiple of 486,691,393,393 is 43993206.

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.

486 x 691 x 393 x 393 = 51867989874

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.

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

691 : 1, 691

393 : 1, 3, 131, 393

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,691,393,393, is 1.

Now, the common factors can be found like this.

486:2x 3x 3x 3x 3x 3

691:691

393:3x 131

393:3x 131

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

3x 3x 131 = 1179

Therefore, the value for common factors is 1179.

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 = 51867989874/(1x1179)

LCM = 51867989874/1179

LCM = 43993206

Thus, we can understand that the LCM of 486,691,393,393 is 43993206.
