Given numbers are 916,861,922,209

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

The LCM of 916,861,922,209 is 75988143924.

Find LCM of 916,861,922,209 with Prime Factorization

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

2 x 458 x 861 x 461 x 209 = 75988143924

Therefore, the lowest common multiple of 916,861,922,209 is 75988143924.

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.

916 x 861 x 922 x 209 = 151976287848

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.

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

861 : 1, 3, 7, 21, 41, 123, 287, 861

922 : 1, 2, 461, 922

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,861,922,209, is 1.

Now, the common factors can be found like this.

916:2x 2x 229

861:3x 7x 41

922:2x 461

209:11x 19

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 = 151976287848/(1x2)

LCM = 151976287848/2

LCM = 75988143924

Thus, we can understand that the LCM of 916,861,922,209 is 75988143924.
