Given numbers are 1,989,529,209

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

The LCM of 1,989,529,209 is 4754123.

Find LCM of 1,989,529,209 with Prime Factorization

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

23 x 1 x 43 x 23 x 209 = 4754123

Therefore, the lowest common multiple of 1,989,529,209 is 4754123.

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.

1 x 989 x 529 x 209 = 109344829

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.

1 : 1

989 : 1, 23, 43, 989

529 : 1, 23, 529

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,989,529,209, is 1.

Now, the common factors can be found like this.

1:

989:23x 43

529:23x 23

209:11x 19

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

23 = 23

Therefore, the value for common factors is 23.

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 = 109344829/(1x23)

LCM = 109344829/23

LCM = 4754123

Thus, we can understand that the LCM of 1,989,529,209 is 4754123.
