Calculate the LCM of 765,116,405,770

Given numbers are 765,116,405,770

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

The LCM of 765,116,405,770 is 61496820.

Find LCM of 765,116,405,770 with Prime Factorization


2 765, 116, 405, 770
3 765, 58, 405, 385
3 255, 58, 135, 385
5 85, 58, 45, 385
17, 58, 9, 77

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

2 x 3 x 3 x 5 x 17 x 58 x 9 x 77 = 61496820

Therefore, the lowest common multiple of 765,116,405,770 is 61496820.

LCM Formula to Find Lowest Common Multiple of 765,116,405,770

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.

765 x 116 x 405 x 770 = 27673569000

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.

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

116 : 1, 2, 4, 29, 58, 116

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,116,405,770, is 1.

Now, the common factors can be found like this.

765:3x 3x 5x 17

116:2x 2x 29

405:3x 3x 3x 3x 5

770:2x 5x 7x 11

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 5x 5 = 450

Therefore, the value for common factors is 450.

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 = 27673569000/(1x450)

LCM = 27673569000/450

LCM = 61496820

Thus, we can understand that the LCM of 765,116,405,770 is 61496820.
