Given numbers are 924,138,690,399

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

The LCM of 924,138,690,399 is 2018940.

Find LCM of 924,138,690,399 with Prime Factorization

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

2 x 3 x 7 x 23 x 22 x 1 x 5 x 19 = 2018940

Therefore, the lowest common multiple of 924,138,690,399 is 2018940.

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.

924 x 138 x 690 x 399 = 35105328720

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.

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

138 : 1, 2, 3, 6, 23, 46, 69, 138

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

399 : 1, 3, 7, 19, 21, 57, 133, 399

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,138,690,399, is 3.

Now, the common factors can be found like this.

924:2x 2x 3x 7x 11

138:2x 3x 23

690:2x 3x 5x 23

399:3x 7x 19

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 3x 3x 7x 23 = 5796

Therefore, the value for common factors is 5796.

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 = 35105328720/(3x5796)

LCM = 35105328720/17388

LCM = 2018940

Thus, we can understand that the LCM of 924,138,690,399 is 2018940.
