Given numbers are 689,893,878,802,198

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

The LCM of 689,893,878,802,198 is 21445924064994.

Find LCM of 689,893,878,802,198 with Prime Factorization

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

2 x 689 x 893 x 439 x 401 x 99 = 21445924064994

Therefore, the lowest common multiple of 689,893,878,802,198 is 21445924064994.

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.

689 x 893 x 878 x 802 x 198 = 85783696259976

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.

689 : 1, 13, 53, 689

893 : 1, 19, 47, 893

878 : 1, 2, 439, 878

802 : 1, 2, 401, 802

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,893,878,802,198, is 1.

Now, the common factors can be found like this.

689:13x 53

893:19x 47

878:2x 439

802:2x 401

198:2x 3x 3x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 85783696259976/(1x4)

LCM = 85783696259976/4

LCM = 21445924064994

Thus, we can understand that the LCM of 689,893,878,802,198 is 21445924064994.
