Calculate the LCM of 686,463,171,352

Given numbers are 686,463,171,352

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

The LCM of 686,463,171,352 is 9559031328.

Find LCM of 686,463,171,352 with Prime Factorization


2 686, 463, 171, 352
343, 463, 171, 176

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

2 x 343 x 463 x 171 x 176 = 9559031328

Therefore, the lowest common multiple of 686,463,171,352 is 9559031328.

LCM Formula to Find Lowest Common Multiple of 686,463,171,352

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 463 x 171 x 352 = 19118062656

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

463 : 1, 463

171 : 1, 3, 9, 19, 57, 171

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,463,171,352, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

463:463

171:3x 3x 19

352:2x 2x 2x 2x 2x 11

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

2 = 2

Therefore, the value for common factors is 2.

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 = 19118062656/(1x2)

LCM = 19118062656/2

LCM = 9559031328

Thus, we can understand that the LCM of 686,463,171,352 is 9559031328.
