Given numbers are 550,291,398,990

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

The LCM of 550,291,398,990 is 95549850.

Find LCM of 550,291,398,990 with Prime Factorization

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

2 x 3 x 5 x 11 x 5 x 97 x 199 x 3 = 95549850

Therefore, the lowest common multiple of 550,291,398,990 is 95549850.

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.

550 x 291 x 398 x 990 = 63062901000

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.

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

291 : 1, 3, 97, 291

398 : 1, 2, 199, 398

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,291,398,990, is 1.

Now, the common factors can be found like this.

550:2x 5x 5x 11

291:3x 97

398:2x 199

990:2x 3x 3x 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 2x 3x 5x 11 = 660

Therefore, the value for common factors is 660.

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 = 63062901000/(1x660)

LCM = 63062901000/660

LCM = 95549850

Thus, we can understand that the LCM of 550,291,398,990 is 95549850.
