Given numbers are 891,716,444,408,690

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

The LCM of 891,716,444,408,690 is 92293094520.

Find LCM of 891,716,444,408,690 with Prime Factorization

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

2 x 2 x 3 x 297 x 179 x 37 x 34 x 115 = 92293094520

Therefore, the lowest common multiple of 891,716,444,408,690 is 92293094520.

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 716 x 444 x 408 x 690 = 79741233665280

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

716 : 1, 2, 4, 179, 358, 716

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,716,444,408,690, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

716:2x 2x 179

444:2x 2x 3x 37

408:2x 2x 2x 3x 17

690:2x 3x 5x 23

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

2x 2x 2x 2x 2x 3x 3x 3 = 864

Therefore, the value for common factors is 864.

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 = 79741233665280/(1x864)

LCM = 79741233665280/864

LCM = 92293094520

Thus, we can understand that the LCM of 891,716,444,408,690 is 92293094520.
