Calculate the LCM of 681,690,189,439,969

Given numbers are 681,690,189,439,969

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

The LCM of 681,690,189,439,969 is 1399208838930.

Find LCM of 681,690,189,439,969 with Prime Factorization


3 681, 690, 189, 439, 969
227, 230, 63, 439, 323

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

3 x 227 x 230 x 63 x 439 x 323 = 1399208838930

Therefore, the lowest common multiple of 681,690,189,439,969 is 1399208838930.

LCM Formula to Find Lowest Common Multiple of 681,690,189,439,969

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.

681 x 690 x 189 x 439 x 969 = 37778638651110

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.

681 : 1, 3, 227, 681

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

189 : 1, 3, 7, 9, 21, 27, 63, 189

439 : 1, 439

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,690,189,439,969, is 1.

Now, the common factors can be found like this.

681:3x 227

690:2x 3x 5x 23

189:3x 3x 3x 7

439:439

969:3x 17x 19

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 37778638651110/(1x27)

LCM = 37778638651110/27

LCM = 1399208838930

Thus, we can understand that the LCM of 681,690,189,439,969 is 1399208838930.
