Given numbers are 991,284,178,667

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

The LCM of 991,284,178,667 is 16707360172.

Find LCM of 991,284,178,667 with Prime Factorization

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

2 x 991 x 142 x 89 x 667 = 16707360172

Therefore, the lowest common multiple of 991,284,178,667 is 16707360172.

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.

991 x 284 x 178 x 667 = 33414720344

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.

991 : 1, 991

284 : 1, 2, 4, 71, 142, 284

178 : 1, 2, 89, 178

667 : 1, 23, 29, 667

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,284,178,667, is 1.

Now, the common factors can be found like this.

991:991

284:2x 2x 71

178:2x 89

667:23x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 33414720344/(1x2)

LCM = 33414720344/2

LCM = 16707360172

Thus, we can understand that the LCM of 991,284,178,667 is 16707360172.
