Given numbers are 521,821,605,821

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

The LCM of 521,821,605,821 is 258783305.

Find LCM of 521,821,605,821 with Prime Factorization

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

821 x 521 x 1 x 605 x 1 = 258783305

Therefore, the lowest common multiple of 521,821,605,821 is 258783305.

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.

521 x 821 x 605 x 821 = 212461093405

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.

521 : 1, 521

821 : 1, 821

605 : 1, 5, 11, 55, 121, 605

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,821,605,821, is 1.

Now, the common factors can be found like this.

521:521

821:821

605:5x 11x 11

821:821

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

821 = 821

Therefore, the value for common factors is 821.

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 = 212461093405/(1x821)

LCM = 212461093405/821

LCM = 258783305

Thus, we can understand that the LCM of 521,821,605,821 is 258783305.
