Given numbers are 817,218,978,916

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

The LCM of 817,218,978,916 is 39888975972.

Find LCM of 817,218,978,916 with Prime Factorization

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

2 x 817 x 109 x 489 x 458 = 39888975972

Therefore, the lowest common multiple of 817,218,978,916 is 39888975972.

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.

817 x 218 x 978 x 916 = 159555903888

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.

817 : 1, 19, 43, 817

218 : 1, 2, 109, 218

978 : 1, 2, 3, 6, 163, 326, 489, 978

916 : 1, 2, 4, 229, 458, 916

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,218,978,916, is 1.

Now, the common factors can be found like this.

817:19x 43

218:2x 109

978:2x 3x 163

916:2x 2x 229

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 159555903888/(1x4)

LCM = 159555903888/4

LCM = 39888975972

Thus, we can understand that the LCM of 817,218,978,916 is 39888975972.
