Given numbers are 247,492,181,680

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

The LCM of 247,492,181,680 is 3739293480.

Find LCM of 247,492,181,680 with Prime Factorization

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

2 x 2 x 247 x 123 x 181 x 170 = 3739293480

Therefore, the lowest common multiple of 247,492,181,680 is 3739293480.

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.

247 x 492 x 181 x 680 = 14957173920

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.

247 : 1, 13, 19, 247

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

181 : 1, 181

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,492,181,680, is 1.

Now, the common factors can be found like this.

247:13x 19

492:2x 2x 3x 41

181:181

680:2x 2x 2x 5x 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 = 14957173920/(1x4)

LCM = 14957173920/4

LCM = 3739293480

Thus, we can understand that the LCM of 247,492,181,680 is 3739293480.
