Given numbers are 603,556,356,821

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

The LCM of 603,556,356,821 is 24497697492.

Find LCM of 603,556,356,821 with Prime Factorization

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

2 x 2 x 603 x 139 x 89 x 821 = 24497697492

Therefore, the lowest common multiple of 603,556,356,821 is 24497697492.

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.

603 x 556 x 356 x 821 = 97990789968

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.

603 : 1, 3, 9, 67, 201, 603

556 : 1, 2, 4, 139, 278, 556

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

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 603,556,356,821, is 1.

Now, the common factors can be found like this.

603:3x 3x 67

556:2x 2x 139

356:2x 2x 89

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.

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 = 97990789968/(1x4)

LCM = 97990789968/4

LCM = 24497697492

Thus, we can understand that the LCM of 603,556,356,821 is 24497697492.
