Given numbers are 687,418,687,973

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

The LCM of 687,418,687,973 is 279412518.

Find LCM of 687,418,687,973 with Prime Factorization

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

3 x 229 x 1 x 418 x 1 x 973 = 279412518

Therefore, the lowest common multiple of 687,418,687,973 is 279412518.

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 418 x 687 x 973 = 191956399866

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

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

687 : 1, 3, 229, 687

973 : 1, 7, 139, 973

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,418,687,973, is 1.

Now, the common factors can be found like this.

687:3x 229

418:2x 11x 19

687:3x 229

973:7x 139

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

3x 229 = 687

Therefore, the value for common factors is 687.

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 = 191956399866/(1x687)

LCM = 191956399866/687

LCM = 279412518

Thus, we can understand that the LCM of 687,418,687,973 is 279412518.
