Calculate the LCM of 543,789,900

Given numbers are 543,789,900

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

The LCM of 543,789,900 is 42842700.

Find LCM of 543,789,900 with Prime Factorization


3 543, 789, 900
181, 263, 300

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

3 x 181 x 263 x 300 = 42842700

Therefore, the lowest common multiple of 543,789,900 is 42842700.

LCM Formula to Find Lowest Common Multiple of 543,789,900

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.

543 x 789 x 900 = 385584300

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.

543 : 1, 3, 181, 543

789 : 1, 3, 263, 789

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,789,900, is 3.

Now, the common factors can be found like this.

543:3x 181

789:3x 263

900:2x 2x 3x 3x 5x 5

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

3 = 3

Therefore, the value for common factors is 3.

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 = 385584300/(3x3)

LCM = 385584300/9

LCM = 42842700

Thus, we can understand that the LCM of 543,789,900 is 42842700.
