Given numbers are 558,771,771,721

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

The LCM of 558,771,771,721 is 103395726.

Find LCM of 558,771,771,721 with Prime Factorization

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

3 x 257 x 186 x 1 x 1 x 721 = 103395726

Therefore, the lowest common multiple of 558,771,771,721 is 103395726.

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.

558 x 771 x 771 x 721 = 239154314238

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.

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

771 : 1, 3, 257, 771

771 : 1, 3, 257, 771

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,771,771,721, is 1.

Now, the common factors can be found like this.

558:2x 3x 3x 31

771:3x 257

771:3x 257

721:7x 103

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 257 = 2313

Therefore, the value for common factors is 2313.

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 = 239154314238/(1x2313)

LCM = 239154314238/2313

LCM = 103395726

Thus, we can understand that the LCM of 558,771,771,721 is 103395726.
