LCM of:

Calculate the LCM of 765,561,810,757

Given numbers are 765,561,810,757

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

The LCM of 765,561,810,757 is 114662790.

Find LCM of 765,561,810,757 with Prime Factorization


3 765, 561, 810, 757
3 255, 187, 270, 757
5 85, 187, 90, 757
17 17, 187, 18, 757
1, 11, 18, 757

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

3 x 3 x 5 x 17 x 1 x 11 x 18 x 757 = 114662790

Therefore, the lowest common multiple of 765,561,810,757 is 114662790.

LCM Formula to Find Lowest Common Multiple of 765,561,810,757

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 561 x 810 x 757 = 263151103050

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

561 : 1, 3, 11, 17, 33, 51, 187, 561

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,561,810,757, is 1.

Now, the common factors can be found like this.

765:3x 3x 5x 17

561:3x 11x 17

810:2x 3x 3x 3x 3x 5

757:757

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

3x 3x 3x 5x 17 = 2295

Therefore, the value for common factors is 2295.

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 = 263151103050/(1x2295)

LCM = 263151103050/2295

LCM = 114662790

Thus, we can understand that the LCM of 765,561,810,757 is 114662790.
