Calculate the LCM of 686,335,412,834

Given numbers are 686,335,412,834

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

The LCM of 686,335,412,834 is 19741138620.

Find LCM of 686,335,412,834 with Prime Factorization


2 686, 335, 412, 834
343, 335, 206, 417

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

2 x 343 x 335 x 206 x 417 = 19741138620

Therefore, the lowest common multiple of 686,335,412,834 is 19741138620.

LCM Formula to Find Lowest Common Multiple of 686,335,412,834

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.

686 x 335 x 412 x 834 = 78964554480

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

335 : 1, 5, 67, 335

412 : 1, 2, 4, 103, 206, 412

834 : 1, 2, 3, 6, 139, 278, 417, 834

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,335,412,834, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

335:5x 67

412:2x 2x 103

834:2x 3x 139

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 78964554480/(1x4)

LCM = 78964554480/4

LCM = 19741138620

Thus, we can understand that the LCM of 686,335,412,834 is 19741138620.
