Calculate the LCM of 685,500,550

Given numbers are 685,500,550

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

The LCM of 685,500,550 is 753500.

Find LCM of 685,500,550 with Prime Factorization


2 685, 500, 550
5 685, 250, 275
5 137, 50, 55
137, 10, 11

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

2 x 5 x 5 x 137 x 10 x 11 = 753500

Therefore, the lowest common multiple of 685,500,550 is 753500.

LCM Formula to Find Lowest Common Multiple of 685,500,550

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.

685 x 500 x 550 = 188375000

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.

685 : 1, 5, 137, 685

500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,500,550, is 5.

Now, the common factors can be found like this.

685:5x 137

500:2x 2x 5x 5x 5

550:2x 5x 5x 11

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

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 188375000/(5x50)

LCM = 188375000/250

LCM = 753500

Thus, we can understand that the LCM of 685,500,550 is 753500.
