Calculate the LCM of 689,803,460,429,989

Given numbers are 689,803,460,429,989

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

The LCM of 689,803,460,429,989 is 32830863780.

Find LCM of 689,803,460,429,989 with Prime Factorization


11 689, 803, 460, 429, 989
13 689, 73, 460, 39, 989
23 53, 73, 460, 3, 989
53, 73, 20, 3, 43

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

11 x 13 x 23 x 53 x 73 x 20 x 3 x 43 = 32830863780

LCM Formula to Find Lowest Common Multiple of 689,803,460,429,989

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 803 x 460 x 429 x 989 = 107980710972420

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

803 : 1, 11, 73, 803

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

429 : 1, 3, 11, 13, 33, 39, 143, 429

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,803,460,429,989, is 1.

Now, the common factors can be found like this.

689:13x 53

803:11x 73

460:2x 2x 5x 23

429:3x 11x 13

989:23x 43

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

11x 13x 23 = 3289

Therefore, the value for common factors is 3289.

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 = 107980710972420/(1x3289)

LCM = 107980710972420/3289

LCM = 32830863780

Thus, we can understand that the LCM of 689,803,460,429,989 is 32830863780.
