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

3 x 3 x 3 x 3 x 11 x 1 x 889 x 3 x 89 = 211490433

Therefore, the lowest common multiple of 891,889,243,979 is 211490433.

LCM Formula to Find Lowest Common Multiple of 891,889,243,979

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.

891 x 889 x 243 x 979 = 188437975803

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

889 : 1, 7, 127, 889

243 : 1, 3, 9, 27, 81, 243

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,889,243,979, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

889:7x 127

243:3x 3x 3x 3x 3

979:11x 89

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

3x 3x 3x 3x 11 = 891

Therefore, the value for common factors is 891.

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 = 188437975803/(1x891)

LCM = 188437975803/891

LCM = 211490433

Thus, we can understand that the LCM of 891,889,243,979 is 211490433.
