The LCM of 689,399,583,897 is 69552483.

Find LCM of 689,399,583,897 with Prime Factorization


3 689, 399, 583, 897
13 689, 133, 583, 299
53 53, 133, 583, 23
1, 133, 11, 23

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

3 x 13 x 53 x 1 x 133 x 11 x 23 = 69552483

Therefore, the lowest common multiple of 689,399,583,897 is 69552483.

LCM Formula to Find Lowest Common Multiple of 689,399,583,897

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 399 x 583 x 897 = 143764982361

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

399 : 1, 3, 7, 19, 21, 57, 133, 399

583 : 1, 11, 53, 583

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,399,583,897, is 1.

Now, the common factors can be found like this.

689:13x 53

399:3x 7x 19

583:11x 53

897:3x 13x 23

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

3x 13x 53 = 2067

Therefore, the value for common factors is 2067.

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 = 143764982361/(1x2067)

LCM = 143764982361/2067

LCM = 69552483

Thus, we can understand that the LCM of 689,399,583,897 is 69552483.
