Given numbers are 281,781,121,973

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

The LCM of 281,781,121,973 is 2348891083.

Find LCM of 281,781,121,973 with Prime Factorization

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

11 x 281 x 71 x 11 x 973 = 2348891083

Therefore, the lowest common multiple of 281,781,121,973 is 2348891083.

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 781 x 121 x 973 = 25837801913

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

781 : 1, 11, 71, 781

121 : 1, 11, 121

973 : 1, 7, 139, 973

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,781,121,973, is 1.

Now, the common factors can be found like this.

281:281

781:11x 71

121:11x 11

973:7x 139

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 = 25837801913/(1x11)

LCM = 25837801913/11

LCM = 2348891083

Thus, we can understand that the LCM of 281,781,121,973 is 2348891083.
