Calculate the LCM of 310,552,682,687

Given numbers are 310,552,682,687

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

The LCM of 310,552,682,687 is 215525640.

Find LCM of 310,552,682,687 with Prime Factorization


2 310, 552, 682, 687
3 155, 276, 341, 687
31 155, 92, 341, 229
5, 92, 11, 229

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

2 x 3 x 31 x 5 x 92 x 11 x 229 = 215525640

Therefore, the lowest common multiple of 310,552,682,687 is 215525640.

LCM Formula to Find Lowest Common Multiple of 310,552,682,687

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.

310 x 552 x 682 x 687 = 80175538080

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.

310 : 1, 2, 5, 10, 31, 62, 155, 310

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

682 : 1, 2, 11, 22, 31, 62, 341, 682

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,552,682,687, is 1.

Now, the common factors can be found like this.

310:2x 5x 31

552:2x 2x 2x 3x 23

682:2x 11x 31

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 31 = 372

Therefore, the value for common factors is 372.

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 = 80175538080/(1x372)

LCM = 80175538080/372

LCM = 215525640

Thus, we can understand that the LCM of 310,552,682,687 is 215525640.
