Calculate the LCM of 786,540,585,489

Given numbers are 786,540,585,489

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

The LCM of 786,540,585,489 is 149898060.

Find LCM of 786,540,585,489 with Prime Factorization


2 786, 540, 585, 489
3 393, 270, 585, 489
3 131, 90, 195, 163
5 131, 30, 65, 163
131, 6, 13, 163

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

2 x 3 x 3 x 5 x 131 x 6 x 13 x 163 = 149898060

Therefore, the lowest common multiple of 786,540,585,489 is 149898060.

LCM Formula to Find Lowest Common Multiple of 786,540,585,489

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.

786 x 540 x 585 x 489 = 121417428600

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

489 : 1, 3, 163, 489

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,540,585,489, is 3.

Now, the common factors can be found like this.

786:2x 3x 131

540:2x 2x 3x 3x 3x 5

585:3x 3x 5x 13

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 3x 3x 3x 5 = 270

Therefore, the value for common factors is 270.

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 = 121417428600/(3x270)

LCM = 121417428600/810

LCM = 149898060

Thus, we can understand that the LCM of 786,540,585,489 is 149898060.
