Given numbers are 891,121,938,872

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

The LCM of 891,121,938,872 is 4008295368.

Find LCM of 891,121,938,872 with Prime Factorization

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

2 x 11 x 81 x 11 x 469 x 436 = 4008295368

Therefore, the lowest common multiple of 891,121,938,872 is 4008295368.

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 121 x 938 x 872 = 88182498096

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

121 : 1, 11, 121

938 : 1, 2, 7, 14, 67, 134, 469, 938

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,121,938,872, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

121:11x 11

938:2x 7x 67

872:2x 2x 2x 109

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 88182498096/(1x22)

LCM = 88182498096/22

LCM = 4008295368

Thus, we can understand that the LCM of 891,121,938,872 is 4008295368.
