Given numbers are 689,924,474,680

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

The LCM of 689,924,474,680 is 8550021480.

Find LCM of 689,924,474,680 with Prime Factorization

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

2 x 2 x 3 x 689 x 77 x 79 x 170 = 8550021480

Therefore, the lowest common multiple of 689,924,474,680 is 8550021480.

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.

689 x 924 x 474 x 680 = 205200515520

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.

689 : 1, 13, 53, 689

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

474 : 1, 2, 3, 6, 79, 158, 237, 474

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,924,474,680, is 1.

Now, the common factors can be found like this.

689:13x 53

924:2x 2x 3x 7x 11

474:2x 3x 79

680:2x 2x 2x 5x 17

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 3 = 24

Therefore, the value for common factors is 24.

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 = 205200515520/(1x24)

LCM = 205200515520/24

LCM = 8550021480

Thus, we can understand that the LCM of 689,924,474,680 is 8550021480.
