Calculate the LCM of 786,768,699,418,687

Given numbers are 786,768,699,418,687

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

The LCM of 786,768,699,418,687 is 1121941480704.

Find LCM of 786,768,699,418,687 with Prime Factorization


2 786, 768, 699, 418, 687
3 393, 384, 699, 209, 687
131, 128, 233, 209, 229

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

2 x 3 x 131 x 128 x 233 x 209 x 229 = 1121941480704

Therefore, the lowest common multiple of 786,768,699,418,687 is 1121941480704.

LCM Formula to Find Lowest Common Multiple of 786,768,699,418,687

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 768 x 699 x 418 x 687 = 121169679916032

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

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

699 : 1, 3, 233, 699

418 : 1, 2, 11, 19, 22, 38, 209, 418

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,768,699,418,687, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

768:2x 2x 2x 2x 2x 2x 2x 2x 3

699:3x 233

418:2x 11x 19

687:3x 229

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

2x 2x 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 121169679916032/(1x108)

LCM = 121169679916032/108

LCM = 1121941480704

Thus, we can understand that the LCM of 786,768,699,418,687 is 1121941480704.
