Given numbers are 326,580,356,421

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

The LCM of 326,580,356,421 is 3542319260.

Find LCM of 326,580,356,421 with Prime Factorization

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

2 x 2 x 163 x 145 x 89 x 421 = 3542319260

Therefore, the lowest common multiple of 326,580,356,421 is 3542319260.

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 580 x 356 x 421 = 28338554080

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

356 : 1, 2, 4, 89, 178, 356

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,580,356,421, is 1.

Now, the common factors can be found like this.

326:2x 163

580:2x 2x 5x 29

356:2x 2x 89

421:421

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 28338554080/(1x8)

LCM = 28338554080/8

LCM = 3542319260

Thus, we can understand that the LCM of 326,580,356,421 is 3542319260.
