Calculate the LCM of 687,906,462,546

Given numbers are 687,906,462,546

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

The LCM of 687,906,462,546 is 207681474.

Find LCM of 687,906,462,546 with Prime Factorization


2 687, 906, 462, 546
3 687, 453, 231, 273
7 229, 151, 77, 91
229, 151, 11, 13

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

2 x 3 x 7 x 229 x 151 x 11 x 13 = 207681474

Therefore, the lowest common multiple of 687,906,462,546 is 207681474.

LCM Formula to Find Lowest Common Multiple of 687,906,462,546

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.

687 x 906 x 462 x 546 = 157007194344

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.

687 : 1, 3, 229, 687

906 : 1, 2, 3, 6, 151, 302, 453, 906

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,906,462,546, is 3.

Now, the common factors can be found like this.

687:3x 229

906:2x 3x 151

462:2x 3x 7x 11

546:2x 3x 7x 13

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 7 = 252

Therefore, the value for common factors is 252.

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 = 157007194344/(3x252)

LCM = 157007194344/756

LCM = 207681474

Thus, we can understand that the LCM of 687,906,462,546 is 207681474.
