Given numbers are 921,603,581,516

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

The LCM of 921,603,581,516 is 18499511772.

Find LCM of 921,603,581,516 with Prime Factorization

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

3 x 307 x 201 x 581 x 172 = 18499511772

Therefore, the lowest common multiple of 921,603,581,516 is 18499511772.

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.

921 x 603 x 581 x 516 = 166495605948

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.

921 : 1, 3, 307, 921

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

581 : 1, 7, 83, 581

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,603,581,516, is 1.

Now, the common factors can be found like this.

921:3x 307

603:3x 3x 67

581:7x 83

516:2x 2x 3x 43

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 166495605948/(1x9)

LCM = 166495605948/9

LCM = 18499511772

Thus, we can understand that the LCM of 921,603,581,516 is 18499511772.
