Given numbers are 821,821,524,821

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

The LCM of 821,821,524,821 is 430204.

Find LCM of 821,821,524,821 with Prime Factorization

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

821 x 1 x 1 x 524 x 1 = 430204

Therefore, the lowest common multiple of 821,821,524,821 is 430204.

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.

821 x 821 x 524 x 821 = 289975134364

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.

821 : 1, 821

821 : 1, 821

524 : 1, 2, 4, 131, 262, 524

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,821,524,821, is 1.

Now, the common factors can be found like this.

821:821

821:821

524:2x 2x 131

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.

821x 821 = 674041

Therefore, the value for common factors is 674041.

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 = 289975134364/(1x674041)

LCM = 289975134364/674041

LCM = 430204

Thus, we can understand that the LCM of 821,821,524,821 is 430204.
