Given numbers are 981,886,355,21

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

The LCM of 981,886,355,21 is 2159877510.

Find LCM of 981,886,355,21 with Prime Factorization

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

3 x 327 x 886 x 355 x 7 = 2159877510

Therefore, the lowest common multiple of 981,886,355,21 is 2159877510.

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.

981 x 886 x 355 x 21 = 6479632530

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.

981 : 1, 3, 9, 109, 327, 981

886 : 1, 2, 443, 886

355 : 1, 5, 71, 355

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,886,355,21, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

886:2x 443

355:5x 71

21:3x 7

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

3 = 3

Therefore, the value for common factors is 3.

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 = 6479632530/(1x3)

LCM = 6479632530/3

LCM = 2159877510

Thus, we can understand that the LCM of 981,886,355,21 is 2159877510.
