Given numbers are 690,554,898

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

The LCM of 690,554,898 is 85817370.

Find LCM of 690,554,898 with Prime Factorization

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

2 x 345 x 277 x 449 = 85817370

Therefore, the lowest common multiple of 690,554,898 is 85817370.

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.

690 x 554 x 898 = 343269480

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

554 : 1, 2, 277, 554

898 : 1, 2, 449, 898

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,554,898, is 2.

Now, the common factors can be found like this.

690:2x 3x 5x 23

554:2x 277

898:2x 449

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

2 = 2

Therefore, the value for common factors is 2.

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 = 343269480/(2x2)

LCM = 343269480/4

LCM = 85817370

Thus, we can understand that the LCM of 690,554,898 is 85817370.

Here are some samples of LCM of two or more Numbers calculations.
