Given numbers are 690,900,717,821,500

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

The LCM of 690,900,717,821,500 is 20308666500.

Find LCM of 690,900,717,821,500 with Prime Factorization

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

2 x 2 x 3 x 5 x 5 x 23 x 3 x 239 x 821 x 5 = 20308666500

Therefore, the lowest common multiple of 690,900,717,821,500 is 20308666500.

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.

690 x 900 x 717 x 821 x 500 = 182777998500000

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.

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

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

717 : 1, 3, 239, 717

821 : 1, 821

500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,900,717,821,500, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

900:2x 2x 3x 3x 5x 5

717:3x 239

821:821

500:2x 2x 5x 5x 5

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 3x 3x 5x 5x 5 = 9000

Therefore, the value for common factors is 9000.

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 = 182777998500000/(1x9000)

LCM = 182777998500000/9000

LCM = 20308666500

Thus, we can understand that the LCM of 690,900,717,821,500 is 20308666500.
