Given numbers are 261,989,559,689

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

The LCM of 261,989,559,689 is 177850881.

Find LCM of 261,989,559,689 with Prime Factorization

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

13 x 43 x 261 x 23 x 1 x 53 = 177850881

Therefore, the lowest common multiple of 261,989,559,689 is 177850881.

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.

261 x 989 x 559 x 689 = 99418642479

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.

261 : 1, 3, 9, 29, 87, 261

989 : 1, 23, 43, 989

559 : 1, 13, 43, 559

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,989,559,689, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

989:23x 43

559:13x 43

689:13x 53

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

13x 43 = 559

Therefore, the value for common factors is 559.

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 = 99418642479/(1x559)

LCM = 99418642479/559

LCM = 177850881

Thus, we can understand that the LCM of 261,989,559,689 is 177850881.
