Calculate the LCM of 682,805,648,489

Given numbers are 682,805,648,489

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

The LCM of 682,805,648,489 is 28994316120.

Find LCM of 682,805,648,489 with Prime Factorization


2 682, 805, 648, 489
3 341, 805, 324, 489
341, 805, 108, 163

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

2 x 3 x 341 x 805 x 108 x 163 = 28994316120

Therefore, the lowest common multiple of 682,805,648,489 is 28994316120.

LCM Formula to Find Lowest Common Multiple of 682,805,648,489

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.

682 x 805 x 648 x 489 = 173965896720

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.

682 : 1, 2, 11, 22, 31, 62, 341, 682

805 : 1, 5, 7, 23, 35, 115, 161, 805

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

489 : 1, 3, 163, 489

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,805,648,489, is 1.

Now, the common factors can be found like this.

682:2x 11x 31

805:5x 7x 23

648:2x 2x 2x 3x 3x 3x 3

489:3x 163

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 173965896720/(1x6)

LCM = 173965896720/6

LCM = 28994316120

Thus, we can understand that the LCM of 682,805,648,489 is 28994316120.
