Calculate the LCM of 665,741,396,811

Given numbers are 665,741,396,811

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

The LCM of 665,741,396,811 is 2776393620.

Find LCM of 665,741,396,811 with Prime Factorization


3 665, 741, 396, 811
19 665, 247, 132, 811
35, 13, 132, 811

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

3 x 19 x 35 x 13 x 132 x 811 = 2776393620

Therefore, the lowest common multiple of 665,741,396,811 is 2776393620.

LCM Formula to Find Lowest Common Multiple of 665,741,396,811

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.

665 x 741 x 396 x 811 = 158254436340

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

741 : 1, 3, 13, 19, 39, 57, 247, 741

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

811 : 1, 811

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,741,396,811, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

741:3x 13x 19

396:2x 2x 3x 3x 11

811:811

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 158254436340/(1x57)

LCM = 158254436340/57

LCM = 2776393620

Thus, we can understand that the LCM of 665,741,396,811 is 2776393620.
