Given numbers are 648,218,554

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

The LCM of 648,218,554 is 19565064.

Find LCM of 648,218,554 with Prime Factorization

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

2 x 324 x 109 x 277 = 19565064

Therefore, the lowest common multiple of 648,218,554 is 19565064.

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.

648 x 218 x 554 = 78260256

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

218 : 1, 2, 109, 218

554 : 1, 2, 277, 554

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,218,554, is 2.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

218:2x 109

554:2x 277

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 = 78260256/(2x2)

LCM = 78260256/4

LCM = 19565064

Thus, we can understand that the LCM of 648,218,554 is 19565064.
