Given numbers are 281,518,517,561

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

The LCM of 281,518,517,561 is 3837927786.

Find LCM of 281,518,517,561 with Prime Factorization

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

11 x 281 x 518 x 47 x 51 = 3837927786

Therefore, the lowest common multiple of 281,518,517,561 is 3837927786.

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.

281 x 518 x 517 x 561 = 42217205646

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.

281 : 1, 281

518 : 1, 2, 7, 14, 37, 74, 259, 518

517 : 1, 11, 47, 517

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,518,517,561, is 1.

Now, the common factors can be found like this.

281:281

518:2x 7x 37

517:11x 47

561:3x 11x 17

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

11 = 11

Therefore, the value for common factors is 11.

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 = 42217205646/(1x11)

LCM = 42217205646/11

LCM = 3837927786

Thus, we can understand that the LCM of 281,518,517,561 is 3837927786.
