Given numbers are 326,120,778,431

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

The LCM of 326,120,778,431 is 3279410040.

Find LCM of 326,120,778,431 with Prime Factorization

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

2 x 163 x 60 x 389 x 431 = 3279410040

Therefore, the lowest common multiple of 326,120,778,431 is 3279410040.

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.

326 x 120 x 778 x 431 = 13117640160

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.

326 : 1, 2, 163, 326

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

778 : 1, 2, 389, 778

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,120,778,431, is 1.

Now, the common factors can be found like this.

326:2x 163

120:2x 2x 2x 3x 5

778:2x 389

431:431

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 13117640160/(1x4)

LCM = 13117640160/4

LCM = 3279410040

Thus, we can understand that the LCM of 326,120,778,431 is 3279410040.
