Given numbers are 821,450,545

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

The LCM of 821,450,545 is 40270050.

Find LCM of 821,450,545 with Prime Factorization

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

5 x 821 x 90 x 109 = 40270050

Therefore, the lowest common multiple of 821,450,545 is 40270050.

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 450 x 545 = 201350250

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

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,450,545, is 1.

Now, the common factors can be found like this.

821:821

450:2x 3x 3x 5x 5

545:5x 109

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

5 = 5

Therefore, the value for common factors is 5.

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 = 201350250/(1x5)

LCM = 201350250/5

LCM = 40270050

Thus, we can understand that the LCM of 821,450,545 is 40270050.
