Given numbers are 681,137,164,272

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

The LCM of 681,137,164,272 is 1040448144.

Find LCM of 681,137,164,272 with Prime Factorization

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

2 x 2 x 681 x 137 x 41 x 68 = 1040448144

Therefore, the lowest common multiple of 681,137,164,272 is 1040448144.

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 137 x 164 x 272 = 4161792576

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

137 : 1, 137

164 : 1, 2, 4, 41, 82, 164

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,137,164,272, is 1.

Now, the common factors can be found like this.

681:3x 227

137:137

164:2x 2x 41

272:2x 2x 2x 2x 17

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 = 4161792576/(1x4)

LCM = 4161792576/4

LCM = 1040448144

Thus, we can understand that the LCM of 681,137,164,272 is 1040448144.
