Calculate the LCM of 681,498,338,208

Given numbers are 681,498,338,208

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

The LCM of 681,498,338,208 is 152838192.

Find LCM of 681,498,338,208 with Prime Factorization


2 681, 498, 338, 208
3 681, 249, 169, 104
13 227, 83, 169, 104
227, 83, 13, 8

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

2 x 3 x 13 x 227 x 83 x 13 x 8 = 152838192

Therefore, the lowest common multiple of 681,498,338,208 is 152838192.

LCM Formula to Find Lowest Common Multiple of 681,498,338,208

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.

681 x 498 x 338 x 208 = 23842757952

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.

681 : 1, 3, 227, 681

498 : 1, 2, 3, 6, 83, 166, 249, 498

338 : 1, 2, 13, 26, 169, 338

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,498,338,208, is 1.

Now, the common factors can be found like this.

681:3x 227

498:2x 3x 83

338:2x 13x 13

208:2x 2x 2x 2x 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 13 = 156

Therefore, the value for common factors is 156.

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 = 23842757952/(1x156)

LCM = 23842757952/156

LCM = 152838192

Thus, we can understand that the LCM of 681,498,338,208 is 152838192.
