Given numbers are 550,554,213,647

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

The LCM of 550,554,213,647 is 20995505850.

Find LCM of 550,554,213,647 with Prime Factorization

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

2 x 275 x 277 x 213 x 647 = 20995505850

Therefore, the lowest common multiple of 550,554,213,647 is 20995505850.

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 554 x 213 x 647 = 41991011700

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

554 : 1, 2, 277, 554

213 : 1, 3, 71, 213

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,554,213,647, is 1.

Now, the common factors can be found like this.

550:2x 5x 5x 11

554:2x 277

213:3x 71

647:647

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 = 41991011700/(1x2)

LCM = 41991011700/2

LCM = 20995505850

Thus, we can understand that the LCM of 550,554,213,647 is 20995505850.
